The Angelica mittens can be matched with the Angelica hat and cowl, the patterns for which are both free.

The Angelica patterns have a moss stitch base with lace insets

Each pattern takes 1/2 a skein of malabrigo merino worsted so you can make any two patterns from a single skein.

Or you can you your preferred heavy worsted or aran yarns that give you gauge.

The patterns are one size with the lace patterns and insets making them quite stretchy.
