Look at these wonderful mittens Melynda made and wrote the pattern for as well.
There is a pair at the store for you to look at.

MOLLY’S MITTENS

Materials: 1 Skein of Malabrigo Chunky

Size 9 US DPN

Some waste yarn

Body of Mitten

CO 28 sts and divide them between 3 DPN. I had 9,9 and 10sts

Row 1-10: *K1,P1 repeat to end* or knit for a rolled edge

Row 11-28: knit all rounds

Row 29: k1 with working yarn, then k5 with waste yarn, then return those 5 sts back onto left needle and knit again using working yarn. Continue in k –stitch for the rest of round

Row 30-54: knit all rounds

Row 55: k2tog until end (14 sts remaining)

Row 56: * k2tog, k1, k2tog *twice, k2

Row 57: k2tog until end, k1

Cut yarn, leaving a 5 inch tail and using a darning needle pull through the 4 sts on the needles and pull top closed. Weave in the tail on inside of mitt.

Thumb

Pick up live stitches while carefully removing the waste yarn. I like to do top and bottom at the same time. Once you have all your stitches take 2 from the top needle and 2 from the bottom needle and put them on a 3rd needle. This left me with 3 sts on the bottom needle and 4 on the other 2 needles. Now you can begin to knit the thumb.

Knit at least 13 rows (more if you have a longer thumb)

Row 14: k2tog and close top of thumb just like the top of the mitt.

***For the left hand mitt repeat the pattern exactly as the right hand except for row 29. Row 29 for the left mitt is as follows; k9 with working yarn, then with waste yarn k5, then return those 5 sts back onto left needle and knit again using working yarn. Continue with k for the rest of round. Continue to knit the rest of the mitt as you did the right hand.

And Voila! Mittens and her very first pattern.
