I'm about ten rows into a pair of Jaywalker socks with the Heartsick yarn, and I can already tell the length of the stripes is too short. Poor hubby is going to have witchy superman socks. It's practically a pinstripe... the stripes are only coming out two rows wide.
For some reason I thought it was (π*sock circumference)*rows of color but I guess Scout and millions of other knitters are right and I'm wrong. Flarbersnout! I had enough trouble trying to get a 20' loop, 30 or more is impossible till I build a warping board. Le sigh.
