This pattern is originally by Julia Vaconsin and was published on the Crochet Me website. I had some difficultly interpreting the pattern and ended up making my first pair such that they were "inside out". I was crocheting from inside the mitten instead of from the outside. I've taken the original pattern and added stitch numbers and a couple other things that ultimately helped me be able to reproduce these mittens.
This pattern fits a 7 inch wrist. I removed two stitches to accommodate a 6 inch wrist.
In this pattern - you will use a foundation single crochet, single crochet through the back loop, chain stitch and slip stitch. All Sc will be worked through the back loop (tbl)
Body:
Fsc 28. Join for working in the round with a sl st at bottom of first fsc, being careful not to twist.
Rd 1: Right-side facing: Sc tbl in first fsc, place marker, sc tbl to end of round (28 sts) - do not Sc in sl st.
Rds 2-10: Sc tbl around.
Rd 11: Sc tbl 1 more in last st of round 10, sc tbl 1 (= first st of round 11), sc tbl 2 in next st, sc tbl to end of round.
Rd 12: Sc tbl without increasing.
Repeat last 2 rounds 4 more times (38 sts) (increase happens on the odd rounds).
Rd 21: Work around to st 34 (4 sts before marker) ch 3 (new beginning of round is the second of those 3 sts), skip 4 sts after marker (rejoin at st 5 of Rd 20) (skip 9 st total).
Work even for another 7 rounds (30 rounds total) or up to desired length, ending with a sl st in first st of round. Fasten off.
Thumb:
Rejoin yarn at thumb opening. Sc tbl in all 9 thumb sts (that were previously on hold), sc tbl 1 in each bottom of 3 ch sts. Continue working in the round for 3 rounds or up to desired length, ending with a sl st in first st of round. .
Fasten off.
Finishing:
Weave in ends. Wash and block. Wear and enjoy.
The first attempt - these are "inside out".
Below are a set of "mother/daughter" mittens. I adjusted the pattern down to fit their wrist sizes.
