I actually have several sets saved in a list on Amazon, and they seem reasonably priced. I haven't purchased them yet, thoughnot because I don't want to splurge...I simply find it difficult to gauge what length I'll need.

Although to be honest, they're priced decently enough that it might not be a bad idea to get a few sets in different sizes.

It really looks great, I even already picked up five or six skeins of yarn for it. It'll be my first time swapping out colors, but it doesn't seem like a difficult thing, so hopefully it goes smoothly!
