I bought this yarn from The Sanguine Gryphon.
I wound it into balls. I knitted a swatch.
I decided on a rotation scheme to prevent pooling, which can be a problem in multi-color yarns, even ones as subtle as this. Yarns that have more aqua are A, and yarns that have more plain blue are B.
A1 A2 A3
B1 B2 B3
A and B trade off every two rows throughout the sweater. In addition, after inch and a half or so, A2 replaces A1. After another inch, B2 replaces B1, and so forth, so that all six yarn cakes are used pretty much evenly. A pin on the knitting shows where I've changed balls, so I can figure out which change I'm on.
I will want to knit the sleeves simultaneously. Yikes! That could get messy.
About 3" into the project, the pattern said "Repeat rows 3 and 4 40 times." I had another shiver of terror. At the end of the forty repeats, I would only have knitted enough to join the sweater to knit in the round.
and this color is not accurate, either
I appealed to sweater knitters I know for encouragement. Margene estimates that a worsted-weight sweater has only about 25% more stitches than a pair of socks, and AutumnBriars on Ravelry has read that a sweater has about as many stitches as three socks.
I can do this.
