My swallowtail shawl is finished, blocked, and photographed for your viewing pleasure!
Needles: Crystal Palace bamboo, size 3
Yarn: Alpaca with a Twist’s Fino in First Frost, 875 yards, 1 skein (I have leftovers)
Finished size: 67″ x 30″ blocked.
I added additional repeats to this pattern to make it larger because I used a smaller needle size to accomodate the laceweight yarn, and I still wanted a full sized shawl, rather than a shawlette. Instead of the recommended 14 repeats of the Budding Lace 2 chart, I did 24. (You can increase this chart by increments of five repeats, but for every additional five repeats, you will need to add four extra stitches between the Lily of the Valley Border and the Peaked Edging to reconcile the math.) After 24 repeats of the Budding Lace 2 chart, I worked the Lily of the Valley Border 1 chart, then the Lily of the Valley Border 2 chart. Then I added two additional rows to the LV Border 2 chart, so that there are six nups worked in that chart, rather than five. This gave me four of the additional stitches that I needed, and I worked an additional increase into the first row of the Peaked edging by increasing after the first yo, before the yo prior to the center stich, after the yo following the center stich, and before the final yo. It sounds complicated, I know, but it really was not. If you are unsure about making changes to a pattern, insert lifelines that you can rip back to if it does not work out or look right. The changes I made are not obvious and do not detract from the pattern.
The finished shawl did come out to be larger than I had anticipated. I am a petite 4’10” so I probably could have done fewer repeats and ended up with an adequately sized shawl. The larger size is not really a problem, though, because the lace is so light and has a wonderful drape.
