First of all, the hand in the picture is not mine, but whoevers it is, they get the credit. I actually used size 9 needles, but it still worked. I've only finished one, but they are so easy!
Start by casting on 30 stitches, and rib stitch for 4 rows. Then switch to stockinette for about 32 rows. Thats how many I did. Finish off by doing 4 more rows of ribbing and cast off. Next step is on the picture, just click to enlarge.
