Interesting experiment with garter stitch versions of vertical lace lattice morphing into right slant lace lattice into left slant lace lattice and back to vertical. And almost one hunk wonder (I had to "harvest" some similar coloured mohair from another project to do the bind off). Not counting the harvested bit it is 3 yarns combined -- a mohair/wool/nylon blend with an orange base, a gold metallic, and a golden curry coloured cotton viscose.
For an idea of the construction and for a better idea of how the lattice works and blends from one to another see images of the prototype moving from vertical to left slant from left slant to right and the overall design/shaping that produces the nice little front or back detail.

The idea of a surprise/retirement shawl for a friends was born a few years back and it sort of floundered around looking for the right yarn & project.
In 2003 while in Taos, I found a few yarn possibilities at La Lana & at Southwest Weaving but when we went to Taos Sunflower (then housed on Marty's house) I found the yarn.

Too many connections to ignore. First the whole Taos magic and its place in my friendship with the recipient, then there was the San Diego County connection as Marty used to live in Encinitas (and work at the Black Sheep) and finally, it turned out that some of the fibre used in the yarn came from Lorraine Powell's place in Ramona.

But I had 3 different colours of yarn in 7 hanks (2 each of a blue and a lavender and 3 of a plum colour) and a vague idea of how to proceed.

Finally I settled on doing a centre back top to bottom triangle and blending the colours by alternating yarn every row. I weighed each of the hanks and then paired the plum hanks with comparable weight hanks of the blue and the lavender.

To add to the surprise element, I opted to do a garter stitch (the better to change colours) version of the collar for the Swiss Vest in Folk Vests. I had done that collar in larger format and produced a very striking almost one hank wonder scarf and I was curious how combining its aggressive increase ratio with a more traditional rate of increase would work out.

The plum & blue combo was my cast on and when I ran out of that combo, I did a bit of garter stitch plain and then worked Bird's Eye stitch pattern in a more typical 5 stitch increase per every 2 rows with the plum and lavender

With an unblocked "wing span" of about 80 inches and a centre back drop of about 38 inches it is a very nice shawl indeed. Instead of trying to write out the increase rate and the Bird's Eye stitch pattern, I just read my knitting aka as knowing where to put the increases and decreases and it worked just fine. When the wingspan measured about 72 inches it became pretty clear that I wasn't going to need to go to the 3rd section although it was a very near thing with the amount of yarn I had to bind/cast off with. End of the day, I've about 12 oz of yarn left over that has potential to surprise someone else.

Just as with the orginal surprise, I did a bit of garter stitch plain before shifting into the next stitch pattern and more typical increase rate. Birds Eye was just too open looking more like Swiss cheese or moth damage with this yarn on this scale. Memory's hazy as to which stitch pattern I used but I isolated a single motif from a stocking stitch based lace pattern and rendered it in garter instead.

Just as with the Surprise shawl, I had to audition edgings from a variety of sources. I already knew that the scale of the knitting demanded a relatively narrow edging and anything with double YOs was not going to work out. I swatched a lot of choices before settling on a modified version of the edging from the Highland Triangle Shawl in Folk Shawls. Careful followers of my knitting adventures will note that the Highland Triangle is the basis of my Swarmy Scotsman which I edged with the 3 holes edging from Heirloom Knitting that I considered (and swatched) for this one before abandoning it.

Just a pic of the swatch for now, more to come.
