I groaned when I read that my latest project required me to do a long tail cast on . For 264 stitches!! That is a lot of stitches if you don't pull off enough yarn and have to tear it all out and start again. I have never had any luck with the instructions that tell you to allow so much per stitch so I usually just wing it. I usually end up with a long piece of yarn leftover, which bothers me almost as much as coming up short. Just because I'm anal that way.
So this time I did not give it any thought whatsoever, pulled off a long strand of yarn and started my cast on. It got pretty squeaky by the end but take a look at this ~
Yup, three inches. Absolutely perfect! This completely satisfies my obsessive nature and has made my day. I think I'll go alphabetize my stash.
