I have a very good friend named Jack who is also a very angry vegan. In my efforts to cover all of my loved ones in hand knits, I decided to knit him a hat. Well, actually I decided that Andrew would knit him a hat. We went to the yarn store and Andrew picked out the yarn and began knitting. The yarn is Classic Elite Premiere, which is a 60/40 cotton/tencel blend. After about 10 hours of knitting, He had about 1 1/2". With only the mildest patronizing tone in my voice, I offered to finish it for him.
Let me just say that I hate knitting with cotton. I know all of the properties that make cotton the wonderful fiber that it is, such as it's ability to keep one cool and supa crisp stitch definition, but these very qualities make it an incredibly bad choice for a hat.
The first problem I came across is the blown out ribbing. The more I attempted to maintain even tension, the more it prolapsed into some unmentionable blob of stringy entrails. Whatever. I figured that once I got to the stockinette, all would be gravy. Like any good knitter, I used a jogless join for the stripes. With wool, this would result in beautifully even stitches. On cotton, it makes a really gross ladder of gaping stitches 100x more fugly than a little jog in the stripes.
In the end it came out okay. A hat was made using no animal products and therefore another vegan is kept warm.
Note: Next year he gets a juicer.
