The Eidos of Table, part two

The essence of a Nakashima-style dining table is that the finished product evokes the original tree. Not in any rustic haphazard fashion but the elegant modern design makes one appreciate the living tree from which the lumber was harvested. It also brings to mind our connection to the paleolithic hominid who put their gathered roots and berries on a fallen log instead of dropping their dinner in the dirt.

Our Cherry slabs would be  book matched, placed side by side with the branch stubs in mirror image. The outside board edges would be left as the tree had grown. The inside edges would be trimmed just enough to join the slabs to make the table top but a void would remain where the growing tree had curved. The two sections would be joined by joined wedges, butterflies. George Nakashima had favored Mahogany with Black Walnut butterflies. As our table was constructed of local Pennsylvania woods, we would use Birds Eye Maple for contrast against the Cherry boards. The birds eye marking would resemble the variegation of an actual butterfly wings and I wanted to maintain a lighter color tone.


Hans Wegner was a Danish contemporary of Nakashima. The finished live edge table would be paired with set of light Maple Hans Wegner wishbone chairs. The wishbone chair combines the shape of a traditional Ming chair with sleek Scandinavian construction. Aside from the designs dating from the same era the maple butterflies and bowed backs would echo each other. 


The workshop had to grow to accommodate the project.
The 10+ foot slabs took over the workshop. Francis decided the solution was a bigger workshop to complete the project. His 12 x15 shed pupped a giant 15 x 20 child. Now he had the original workshop for tools and the new area for woodworking. No reason for a workshop to look utilitarian, along with expansion came french doors for better light and air flow, a deck to rest from his labors and a stone patio with a fire-pit to burn the scrap. It’s not a workshop it’s a cottage,
dubbed “Labrotorio Artigianale Di Francisco” with it’s own address 118b.

Sealing, smoothing and aligning the rough slabs took every day of several vacations in the new space. A snapped plumb line from end to end determined the minimum wood to remove to join the two slabs. Just a small sliver off the side opposite the branch stub would permit the two boards to be joined but maintain a partial void  towards one end. To support and level the heavy slabs 2x2 stringers cut two inches shorter than the table width and attached to what would be the bottom of the top.

 Once the wood was stable, it was butterfly time. A half-dozen butterflies would rest in this table top. Each butterfly in the table required both a carved insert and a matching carved divot. 

Francis estimated it took him seven hours to carve out and assemble each butterfly. He started out with a paper template. The paper template was scribed onto the cherry table top and then glued onto the Birds Eye Maple stock. He sawed out the block and hand beveled the edges. The table top was hand carved to crisply set the dimensions. With a Forsner bit he set the rough depth and removed some initial waste and using  a router he removed more waste. The delicate work of carving just to but not beyond the outline and beveling out the sides of the divot was completed with hand chisels. 

The bevel and shaping  of both the divot and the insert had to be precise in slant and proportion. The butterfly insert must be slightly larger at the base than the opening of the divot but precisely the same dimension as the base of the divot. When knocked into place the two units snap tight with just a film of glue between. The opposing angles of the butterfly's wings drawing the two slabs together. Delicate butterflies joining two heavy slabs of lumber into one elegant table top.   The stringers running across the bottom  counterbalanced by the butterflies snapped and glued in place on the top, the opposing forces preventing the table top from buckling or bowing.
 
Finally, the top is complete and the finishing commences. To a man learned in the ways of French Polish, a finish cannot be rushed. First a seal coat, sand it away, then base coat, sand that down, then a top coat, sand that smooth, then the finish polish, which must be buffed to a gentle glow. We are still at the buffing stage. Will he ever be satisfied? Hmmm...


And between the butterflies and the finish, we encounter a design dilemma and make another  trip to Aldenville.  Should our table base replicate the Conoid (cantilevered) style or the Minguren (slab) style? In any case  materials must be sourced and it’s back to visit Dan Droppa.

When we arrive at Aldenville Lumber http://www.avlumber.com/ there is a new addition to the site. In the center of the lot is a pen filled with Japanese Quail. Tiny spotted birds wandering around, squawking at us and dropping tiny spotted eggs at random. Dan tells us that he bought some lumber from a farmer and picked up some baby Quail while he was there. The minute birds leave him eggs every day, which he reports he greatly enjoys with salad.

Francis has speced a number of lengths and sizes of Cherry from which to make the base. Once again, all hands on deck become involved in the selections, trimming and planing. They pull blocks and boards from the stacks for Francis’ approval then cut the lumber to size and plane the rough surface smooth. We are only charged for the segments we request but the remainders are thrown in as well, plus a pile of Cherry 2x2s to use as checks when stacking the wood.  Amazed at the service we have received, we begin to drive away, only to have Dan run after us. His hands are full, “Would you like a dozen quail eggs to take home?” 

Francis contemplates his creation.

How can an Old Goat Learn a New Trick with New Tech?

Say Brioche to most people and they imagine elegant soft textured bread. Brioche to a knitter is similarly elegant soft textured knitting. Brioche knitting is rumored to have ancient Middle Eastern roots. The etymology of the term is equally vague.
Not this kind of Brioche...
It may be a reference to the shape of a brioche roll, two pieces, one stacked on top the other, like brioche  knitting has two yarns stacked one on top of the other. How it went from the Middle East to France is unknown.

This kind of Brioche...
When I discovered the shaker knit sweaters I’ve always loved were brioche stitch I set myself to learn the technique. Never have I been so confused. Books did not have a basic description. Written instructions were unintelligible text:  brk, brp and brkyobrkypobrkyo. At my local yarn store the resident expert was equally confused by the written instructions. Further more, she had never made anything in the two-color technique I wanted to master. It was frustrating.

Frustrated but undeterred I investigated three different types of on-line tutorials:  U-tube demos; a professional training video and a professional E-book (http://knitfreedom.com/classes/brioche). There are multiple u-tube videos on brioche stitch. Some were amateurish in the worst sense, poor audio and/or video quality or simply tedious. If you make mistakes taping an instructional video, start over for pete’s sake! The one which was clearest and seemed to the point was in a language which I do not speak so I was lost, again. A commercial instructional video which I purchased and downloaded had excellent production quality but suffered in two aspects: prolonged introductions and an inflexible format.  The expert explaining the technique unfortunately looked like the proverbial deer in the headlights and her extended verbiage-only descriptions were both uncomfortable and tedious.  Being an expert does not necessarily make one a teacher. In addition, the continuous video made it difficult for me to skip the items I easily understood and repeat the items for which I needed more time.

The winning way for me to learn the technique was the e-book. The e-book features short text introductions with concise and well focused videos. Each short video clip has a descriptive voiceover while the technique is displayed. This creates an effective learning tool by providing a conceptual framework, then demonstrating the concept with detailed explanation. As each segment is a separate clip, you can concentrate on just the skill you want and repeat until you have mastered it. This particular E-book like many others in this format is available both on-line and as a downloadable document, so that you can continue practice whether on or off the internet. There is even a receive a mobile version E-Book designed to run on a  smartphone, iPad, or Kindle so the instructions can go with you anywhere. Way cool! From now on when I want to learn how to do something my search will be for an E-book on the subject.
   
The E-book format enabled me to brk and brp with the best. If you have any interest in mastering Brioche waste not your time and proceed directly to http://knitfreedom.com/  for their excellent Beginning and Intermediate Brioche Knitting  video e-book (http://knitfreedom.com/classes/brioche). I am thoroughly impressed with knitfreedom.com and have placed myself on the waiting list for their upcoming advanced brioche e-book. They have a similar tutorials on a variety of other knitting techniques as well as some free patterns.

[Note to reader:  from here on it’s all about knitting.]


 
What makes Brioche really neat is - - it is a kind of double knit with two layers of fabric interwoven in a ribbed pattern. Each row is completed in two circuits , in two-color brioche once in each color. Basic Brioche is a kind of 1 x 1  rib, working in the round, the main color would be the knit stitches while the contrast color would be the purl stitches. What makes Brioche unique is you alternate a worked stitch with a slipped stitch. When working the knits you slip the purl stitches and simultaneously wrap each purl stitch with a yarn over.  Similarly when working the purls you slip the knit stitches and simultaneously wrap each knit stitch with a yarn over. In the knit or purl process the yarn over is worked together with the stitch. This is a radical departure from usual knitting, the yarn overs in Brioche are not individual stitches but are accessories to the worked stitches.

Dear Spouse was also very taken by the appearance and texture of two color brioche and requested a neck-warmer/hood/balaclava. To this end I’ve designed a simple tube garment which can be tucked under the coat collar and adjusted for comfort. If the weather is really nasty, just pull it up over the ears or all the way over the head. The doubled rib of the brioche stitch provides enough resilience to stretch from neckline to skull and return to the original shape.

Note about casting on:  Most brioche patterns I’ve read suggest unusual cast on and bind off techniques, often involving sewing. The rationale for these techniques eludes me. If I wanted to hand sew I be making crewelwork not knitting. Use the cast on and bind off with which you are most comfortable. My personal preference is the Old Norwegian/Twisted German Caston with a Twisted Stitch Bind off, as they create a softly roped edge.


Franiclava

Materials:  16" circular needles in size 10
and another larger needle just for the cast-on
One marker
3 oz each of two contrasting worsted weight yarns
    The yarns used in the sample are Brown Sheep Lamb’s Pride Worsted (85% Wool/15% Mohair) in Onyx and Paton’s Classic Wool Worsted (100% Wool) in Grey Marl

Directions:
Cast-on in Old Norwegian/Twisted German [see reference] 60 stitches loosely using a larger needle.  Transfer the stitches to the 16" size 10 circular needle. Connect the two ends of the cast-on row without twisting the row and place a marker at the beginning of the work. The marker serves as a reminder that a half-round or round has been completed and it is time to change yarns.

Round 1 - - knit plain

Round 2a - - Brioche setup, alternately knit a stitch and slip the next with a simultaneouswrap of yarnover - - in knitting shorthand this is written as:
      (k1 yf sl1yo yb) to marker sm switch yarn 
Round 2b - - Brioche setup for the second color, alternately slip a stitch  with a simultaneous wrap of yarnover and purl the next one - - in knitting shorthand this is written as:  
     (p1 sl1yo yf) to marker sm switch yarn

Round 3a - - Knit each knit  stitch together with it’s contrasting yarnover wrap and slip each purl stitch wrapping the yarn over the needle as you slip the stitch. Knitting the stitch together with it’s wrapped yarnover if called a Brioche knit - - in knitting shorthand Brk1. This row in shorthand is:   
     (Brk1 yf sl1yo yb) to marker sm switch yarn 
Round 3b - - Purl each purl  stitch together with it’s contrasting yarnover wrap and slip each knit stitch wrapping the yarn over the needle as you slip the stitch. Purling the stitch together with it’s wrapped yarnover if called a Brioche Purl - - in knitting shorthand Brp1. This row in shorthand is:  
    (Brp1 sl1yo yf) to marker sm switch yarn
 
Continue alternating Round 3a and 3b, until the tube is 16" long. Bind off using your preferred technique or the suggested Twisted Stitch bind off, [see reference].

Twisted Stitch Bind off  
detail of bind off showing rope effect
Can’t find this anywhere but it can’t be unique.  At the end of a round when you are ready to bind off:   knit one and place the new knitted stitch back on the left needle, knit 2 together through the back loop and place the new the knitted stitch back on the left needle while twisting the new stitch around, [the same maneuver as in a cable cast-on]. Continue in this fashion, placing each subsequent new stitch back onto the left needle in a twisted configuration and knitting the twisted stitch and the next in line together through the back loop. The double twist makes this  bind off wrap over the edge of the last row of the knitting project, similar to a i-cord bind off or crochet crab-stitch edging but stretchier.
