I decided that the Electric Blue Cassidy sweater I knitted for Emily needed a pair of matching fingerless mitts, so I designed and knitted a pair using Chart C from Cassidy on the back of the hand.

Here is a rough pattern that assumes you have knitted a pair of fingerless mitts before. I do not give a pattern for the cable because I used the pattern from Cassidy.

On 4mm dpns, cast on 44 stitches

Knit 24 rounds of K3, P1 ribbing

Begin cable pattern and thumb gusset increases:

For left mitt, K1, pm, m1R, K1, m1L, pm, K1, P1, K3, work Cassidy Chart C, (K3, P1) x 5

For the right mitt, K3, work Cassidy Chart C, K3, P1, K1, pm, m1R, K1, m1L, pm, K1, P1, (K3, P1) x 4

Knit one round in pattern (knit the knit stitches, purl the purl stitches, cross cables on cable rounds).

Continue increasing every other round. I worked the K3, P1 ribbing into the thumb gusset as the stitches allowed. Note that the number of stitches between the m1R and m1L will increase by 2 after each increase round. Keep increasing until you have 21 stitches between the markers.

Knit one more plain round, and place the gusset stitches on waste yarn.

Join to continue knitting the hand in the round, adding one stitch where that first thumb gusset stitch would have been, and knit in pattern until the mitt is the length you desire. I knitted 7 full Chart C repeats and 3 rows of an 8th repeat (8 cable crossing total), then cast off using the sewn cast off.

Put the gusset stitches on dpns and pick up 5 stitches along the thumb hole. (I knit the picked-up stitches through the back loop to close up any holes.) Move the first 2 knit stitches and the last two knit stitches of the gusset onto the needle with the picked-up stitches. The last to knit stitches that you move to the “picked-up” needle will become the beginning of the round.

Work thumb decreases as follows:

Rnd 1: SSK, K2, P1, K2, K2tog, work needles 2 and 3 in pattern

Rnd 2: SSK, K1, P1, K1, K2tog, work needles 2 and 3 in pattern

Rnd 3: Knit the knits, purl the purls

Rnd 4: SSK, P1, K2tog, work needles 2 and 3 in pattern

Rnd 4: Knit the knits, purl the purls

Rnd 5: P3tog, work needles 2 and 3 in pattern

Rnd 6: Knit the knits, purl the purls

Cast off. Weave in ends.
