I’ve just put up errata for my Apple Cider Mittens. There’s an increase missing in round 8 which is the most important problem. The rest wouldn’t keep you from getting it right, they are fairly obvious mistakes.

Cuff
Rnd 10: ….. 5 groups of 5dc, 1 sc. (Not 5 sc).
Hand
Rnd 1: … ch 1, sc around bottom edge of foundation round (NOT: sc blo around, there are no back loops there)
Rnd 8 is missing an increase: …. Ending with 1 sc blo in next sc and 2 sc in last st. – 47 sts.
Consequently there’s the same problem in rnd 12 which repeats rnd 8.
