These are classic thumb mittens for a toddler, sized for about 2 to 3 years, and you knit them flat on two straight needles. No double points, no circulars. The tutorial is from So Woolly, and the full written pattern with measurements is free on the So Woolly website. One mitten takes around 30 grams of worsted yarn. If you can knit and purl, you can make these.
How to knit mittens: the short version
- Cast on 30 stitches on 4 mm needles.
- Work 13 rows of knit 1, purl 1 rib.
- Switch to 5 mm needles and work stockinette.
- Increase on both sides of the thumb stitches every other row.
- Knit the thumb on its own 9 stitches, then close it.
- Pick up at the thumb base and knit 9 rows for the hand.
- Decrease to round the top, bind off and sew the seam.
Why knit mittens flat?
Most mitten patterns are knitted in the round, which means juggling four or five double-pointed needles. Flat mittens skip all that. You knit one piece back and forth, fold it and sew one seam up the side and around the top. For a beginner, or anyone whose hands do not love tiny needles, that is a big relief. The seam sits on the outer edge where a little hand will not feel it.
Yarn and needles
Use a worsted weight wool or wool blend. Wool stays warm when it gets damp, which kids' mittens always do. Superwash wool goes in the washing machine. Acrylic works and is cheaper, though it is less warm. The smaller 4 mm (US 6) needles make the cuff snug so it hugs the wrist. The 5 mm (US 8) needles give the hand some room. Pick a light or mid color for your first pair so you can see each stitch clearly.
Sizing up or down
This size fits roughly 2 to 3 years. Measure around the child's hand at the knuckles. For a bigger child, cast on a few more stitches and knit a few more rows before the thumb and before the top shaping. Hold the mitten up to the child's hand as you go. The hand should reach the tip of the little finger before you start the decreases.
Make them a pair
So Woolly notes the right mitten is almost the same as the left. Follow the written pattern for the small change. Knit both mittens before you sew either one, so you can match row counts. For little ones who lose things, crochet or braid a long cord and sew one end to each cuff, the old-fashioned mitten string.
Common problems
- Holes beside the thumb. Pull the picked-up stitches snug, and close any gap with the yarn tail when you sew up.
- Thumb too short. Add a pair of rows before you close it. Toddler thumbs are short, so do not overdo it.
- Cuff too loose. Check you used the smaller needles for the rib.
- Bumpy seam. Use mattress stitch on the right side and keep the tension even.
