Using worsted weight yarn cast on 23 (25, 27) stitches on size 5 needles. These mittens work great for grown ups too, add an additional two stitches to make small women size, etc.
Row one: P1 (K1, P1) across.
Row two: K1 ( P1, K1) across.
Repeat rows one and two until piece measures about 3inches ( increase length of cuff if you are making larger mittens) . End by working row 1.
Shaping: Row 1: Knit (13, 14, 15) stitches. Place marker, increase twice, place marker, knit across. (30,32,34)stitches.
Row 2: purl across
Row 3: Knit to marker, increase, knit to within 1 stitch of marker, increase, knit across: (32, 34,36) stitches.
Repeat rows 2 and 3: (1,2,2 ) times
Work until piece measures 5inches from cast of edge, end by working a purl row.
Knit to marker and slip these (13,14,15) stitches onto a stitch holder. Add on 1 stitch, knit to marker, turn. Add on one stitch and slip these remaining (10,12,12) stitches onto another stitch holder.
With right side facing, slip stitches from 1st stitch holder onto needle. Pick up a stitch in each of the added on stitches at the bottom of the thumb ( this is hard. sometimes even when I do it just right I am left with a small hole to stitch up). Slip stitches from 2nd holder onto other needle. Knit across.
Work until piece measures about 6.5 inches, end by working a knit row.
Purl (14,15,16) stitches, place marker, purl across.

Row2: purl across.
Repeat rows 1 and 2 ( 1, 2, 3) times. (20,18,16)sts.
Next row: k2 tog across ( 10,9,8)sts.
Cut yarn leaving a long end for sewing. THread yarn needle, weave through remaining stitches, pulling firmly to close hole, weave seam.
Now- do it all over again for the second mitten. Weave closed any holes at the base of the thumb ( Hazel very sweetly showing you where she needs some stitches). I suggest finger knitting ( or braiding) a cord to hold the two mittens together and wearing it through the arms of the coat. Its a pretty sad day when a handmade mitten goes missing.
