I go with worsted and acrylic usually. A single Red Heart Super Saver skein can get me through the main body of a single pony, wings included.

If, um, you'll forgive my ignorance, do you think you could tell me how that sort of information helps? I've always gone straight into Make The Thing mode without much pause. I know yarn weight and stitch gauge help determine an item's size, but I don't rely on gauge much and as far as hook size goes I tend to match to the yarn. I get that a lighter weight of yarn might yield a smaller size, but does it also mess up the pattern or something?

Sorry to bug you with questions like that, I just didn't get much formal crochet education, and I figure that if you're asking then you probably know why you need it. Knowing that should help me remember to include that sort of information at the beginning of the pattern in the future.

*ahem* Anyway, thank you so much ^_^ I'm happy to share the pattern with y'all.
