I'm going on my first SEX expedition tomorrow and would love some advice. I have a few projects in mind that I want to buy yarn for, but what about just general enhancement on the stash? If you see something that you love, but don't have a project in mind for it, how much do you buy? Saying that though, I'm unlikely to be knitting any jumpers soon, so I'll probably limit my quantities to enough for scarves (I like knitting scarves and trying different patterns and techniques). I'm also hoping to get some good knitting needles as mine are just el cheapos.
