Once my daughter discovered the balls of self-striping yarn she was done with plain colored socks. Done. Especially when I explained that this particular ball would make rainbows.
If I had it to do over again, (and I'm sure with a little girl who loves hand knit socks, I will) I might try the snip method to really be able to place the heel exactly where it would fit the best. As it is, these are just a smidge too long because I kept feeling like the foot looked too short.
In the end I can't say that I love how the afterthought heel sits compared to a good ole' heel flap heel, but it's a nice trick to know when I want to get all OCD on some self striping socks.
Oh. And smidge too long be damned, she loves them.
