I think because I enjoy knitting the same thing over and over again, I avoid doing the math and just wing it. (Please note that this is said with heavy sarcasm) It is easy when it's my sweaters. I know what to do if I want a really well fitting sleeves. I know exactly the number of rows to leave between decreases and it hasn't mattered the gauge. Yet. On kiddie sweaters, not so much.
This pretty red sleeve on Cassie's current sweater, took 4 tries to get right. First I used needles that were the same size as what I knit the sweater on. This is a no brainer for me. Go up one needle size. All those socks make a difference. I forgot.
Second, it narrowed too fast. A healthy third would have been a straight tube.
Third, I forgot to add the extra stitches I use to close up any funky holes on the first round.
Fourth time was the charm. I had the needles right. I had the decrease rate right. I did all the stitches.
Its lovely. And it only took the better part of Saturday.
Sunday morning while watching 1 episode of NCIS and 1 of Gracepoint, no commercials, I knit the second sleeve.
The knitting is complete on the pretty red sweater.
Next button bands and a collar and the embroidery. I am looking forward to this!
