Every year for the last four, I've gone to Stitches West, which is described on their FAQ as a "fiber experience" but is really just a huge yarn/knitting/crochet/weaving/spinning/etc. convention. Usually I come back with a huge bag of yarn and various associated sundries. This year was no exception!
This year the only yarn I got was some lace from Sincere Sheep, and some 2-ply and worsted from Miss Babs. I also picked up some cool knit blockers from Knitter's Pride, a shawl pin, and surprisingly, some sewing pins.
