How Much Yarn for Long Tail Cast-on Starts

There are a few different ways to cast on, but I always use a long tail cast on. I like the neatness of the cast on edge and it’s stretchy, just what you want for a cover that has to stretch over a round teapot.

I have seen in some knitting discussions that some people find it hard to guesstimate the length of the tail they need to obtain the required number of stitches. One lady said she even used two balls of yarn of the same colour so that she could have a tail of an unlimited length, cast on and then cut the second ball loose. Humm, more ends to sew in.

I had no idea it was such a bother, because my Grandma had taught me how to guesstimate my tail when she taught me to knit. I thought I'd share a photo of her with you, she's not with us anymore; her name was Grandma Hall.

The rule of thumb is that 30cm of DK yarn, which is about the length of your knitting needle will comfortably give you about 22sts with a bit left over for stitching up. So, if you want 60sts, you measure the yarn against your needle 3 times and hey presto you have enough.

The same rule applies to Aran yarn or double thickness DK yarn using 5.5mm knitting needles. 30cm of yarn would comfortably give you 14sts, so when I want to cast on 28sts to start a cosy, I measure my knitting needle twice with a little extra for sewing up.

Give it a try and see if this trick works for you. Good old Grandma Hall!
