This pattern works will with most any 50 gram worsted weight ball of yarn.

Errata: In the thumb gusset instructions, it says to repeat the three thumb gusset steps and gives a new stitch count for each repeat, but it did not clarify the number of stitches you are actually knitting between the M1s. In the first repeat, you’re doing K5, in the second you’re doing K7 and in the last, you’re doing K9. I’ve updated the pattern to reflect this clarification. 5/12/11
