Here's the second square from April Afghan Sunday. It's the Hanna Burns square, a.k.a. "the DNA square."
In the magazine photo of this square, the garter stitch borders clearly flare; and no wonder, since they are worked on 62 stitches with size 8 needles! I worked 48-stitch upper and lower borders, and the square is quite true. The central braid really draws in a lot, so I worked border increases/decreases about every other stitch in that section. Fidgety business: As usual for me, I ended the lower border with a RS increase row, then worked a WS foundation row; I also began the upper border with a RS decrease row, working decreases into cable crossings.
Some knitters find it confusing that the righthand "DNA strand" (Chart B) begins with Row 1 but the lefthand strand begins with Row 17. The tricky bit, for the spatially challenged, is to realize that when you are working on the wrong side, those positions are reversed. So for the second row of the patterned section, you have to work Row 18 of the chart for the first strand you come to, then work Row 2 for the second strand. Fidgety business: The only time this threw me was when I was working the WS foundation row; I should have worked Row 16 first and then Row 32, but I got them backwards on the first try and had to tink.
The square was a little narrow before blocking (11 1/4"), so I stopped a bit short in length also (11 1/2") to keep the proportions square, and it wet-blocked to 12" x 12" very nicely.
The consistency hobgoblin demands that I riff for a while on working all the 1/1 twists in such a manner that no individual stitches end up twisted. Here are my methods:
1/1 RT: This one is okay as written, but it's hard on my right wrist. I prefer to sl 2 tog kwise, then transfer both sts back to LH needle (this exchanges the positions of the 2 stitches and also changes their mount direction). K1 tbl twice.
1/1 LT: Sl 1 pwise, Sl 1 kwise, then transfer both sts back to LH needle (this changes the mount direction of the second stitch; otherwise it would get twisted by being worked through the back loop). Now with RH needle behind work, k 2nd st tbl, then k 1st st in front loop.
1/1 RPT: Also okay as written, but I like to sl 2 tog kwise, transfer both sts back to LH needle (as for the RT), K1 tbl, P1 tbl.
1/1 LPT: Reverse the mount of the second stitch as for a 1/1 LT. Now with RH needle behind work, p 2nd st tbl, then k 1st st in front loop. (BTW, it's much easier to dig out that purl stitch once it's been turned around, too.)
One last remark: Those strands aren't actually helixes. They don't spiral, they merely rotate one direction and then the other, because the twists in Row 13 and 29 go opposite directions. If you want them to truly spiral, replace the left twist in Row 29 with a right twist.
