For figuring out how long to make your tail in a long-tail cast on? When I began knitting, I was taught to wrap the yarn around the needle as many times as your cast-on stitches. Most of the time, that’s a good rule of thumb, but if you are knitting something with many stitches to cast on, it’s a pain to wrap so many times. On top of that sometimes,I end up with HUGE tails. I don’t mind cutting off and wasting a fe inches of extra yarn, but a foot and a half extra (for the 158 stitches I just cast on), is ridiculous!
I figure some of you have a better way!
