A Formula for the Long Tail Cast On's Tail

The Long Tail Cast On was the first way I learned how to cast on in knitting, and it is a great method for a lot of applications.

But it had one major problem to me:
estimating how *long* a tail to begin with.

Oh, I'd heard of wrapping the yarn around the needle and other ways to try to figure it out, but when I needed to cast on 240 stitches the other day for a cowl, I assumed I could just use my knitted cast on instead.  It doesn't begin with a long tail, so no worries about it being too short.

But the knitted cast on didn't give me that nice edge that the long tail cast on does, so I decided it was time to search the internet for an answer.

Lo and behold, I found it on this blog:  Taking Time to Smell the Roses, at  Her entry, The Mathematics of Long Tail Cast On, was exactly what I needed.

So, if you ever need to know, and Mr. Google hasn't directed you to Jackie's post, here is the formula in a nutshell:

[ (Number of stitches) X (mm needle size) / 8 ] + some extra for weaving in later.

This gives you the number of inches of yarn you need for your tail.

I do suggest you pop over to the original blog post and enjoy the entire entry:

Thank heavens, once again, for the power of the internet and sharing, generous people like Jackie.  ♥
