I guess I didn't understand the whole gauge thing in knitting (which is why when I got 3/4 of the way through my most recently started project, which was intended to be an Adult Medium, it fits Jessie pretty good.......).
Until I went to my Mom's LYS with a pattern in hand, and they helped me pick the yarn. My only requirements? It had to be a specific color - I don't care what the fiber is, how to care for it, it just had to be a specific color.
Too bad I decided to switch patterns after bringing the yarn home, but a quick call up there (hey - she told me if I had any questions to give her a call) and they verified that the yarn I purchased should work with the pattern I FINALLY decided on. With different sized needles than what I purchased of course:)
Another call up there this afternoon to ask them to hold another skien of yarn for this project, and I should really be good to go.
