errata
Mitt instructions should read:
Step 1: Using provisional cast on, CO 52 (60) sts.
Step 6: Rearrange sts so that needle tips are now facing bottom of mitt. Using MC, graft tog 21 (29) sts from each side at the bottom of the mitt. 32 live sts rem (16 on each needle) in the middle of the mitt.
Step 10: Optional edging: On top of mitt and with MC, PU & K 46 (54) sts, or one picked-up st for each stripe. Join into round, taking care not to twist sts, and loosely BO all sts on next round in P st.
Thanks to katrog for noticing the error.
