This is a picture of the front of the sweater. I managed to get the button band to lay flat because it was sticking to the carpet.
I'm not sure I understand blocking. Would be willing to try it, but how do you do it?
To sew the button band on, I first laid it out flat and pinned it to the front, then I discovered that every few rows I would get a pucker on the sweater side, so instead of sewing every row on the sweater side, I would skip a row every once in a while. This prevented the pucker and made sure everything lined up nice and straight.
Here are the sleeves (inside out they just kind of knitted up that way) I am knitting both at the same time using 2 circular needles. Not sure I understand how I would add more stitches to the cable other than to knit across them one way, then back to the beg and one more time so you end up with 2 extra rows of cables. (turning work before and after cable) The yarn I'm using is worsted weight Simply Soft yarn.
No I did not have a salvage stitch, not in the instructions, so I didn't think of it. This is the first sweater I've ever knitted. I'm a beginner and have only done scarves, hats, and socks up until now.
