YARN: 3.5 oz. ball of Vanna's Choice (LionBrand.com), 100% Acrylic (makes two pairs).
HOOK: G/6; 4.0 metric; 8 UK.
Basically a tube of 13 double crochet rows, I started and ended with a row of 22 single crochet.
The thumb opening was started on row 4. Instead of joining onto the first stitch of that row, I single crocheted back along the row. I did that three times before continuing with my tube. I finished by crocheting around the thumb hole.
