I personally used size 9 dpns, however I am a somewhat tight knitter so you may use a size 8 as this yarn calls for.

Correction to the twisted rib pattern, R3: P2, K2, P2, (K2tog but don’t drop the stitches from the left needle, knit the first stitch again, drop both stitches), repeat from *

Correction to left mitt-all rows should start P2, K2, not K2, P2
