9 rows of ribbing at the cuff.

10 repeats of lace pattern before starting right/left directions

After the 15th repeat of the lace pattern you’ve got 10 + 4 increases + 4 rounds even. On the next round 2, separate for the thumb. Complete that repeat of the lace pattern and one more, then switch to rib. 9 rounds of ribbing.

6 rounds knit for the thumb + 3 of ribbing.

Used Jenni’s stretch cast off.

The pattern contains some omissions, so you need to read the directions for the second mitt to complete the first one. Pattern has been updated by the designer.
