First of all, I didn't write down much of the pattern while crocheting so this is all from memory and counting stitches on the finished gloves. If you find something that I should change or add to the pattern please send me a note!
I used a 4 mm crochet hook and acrylic yarn for 8 mm hooks.
Make the "wrist part" first. You might have to make less or more rows depending on what yarn/hook you're using or how big your arms are.
The whole "wrist part" is crocheted only in the back loops of the previous row, to get the ribbed look.
Start with yellow yarn.
1: Ch 26, turn
2-9: sc 25, ch 1, turn
Switch to red yarn
10-35: sc 25, ch 1, turn
Fasten off and leave a long end, and stitch it together.
Now the "glove part". It might look complicated (at least that's what I though when I first found a pattern made with this technique), but if you try you will quickly get the hang of it. And the result looks really good!
You make "sets" of one single crochet and one chain to make small arcs, and then you make the next row's sc's in the arcs. (Not in the stitch, but in the hole under the chains)
Be careful to count the sets though, since it's easy to lose track and hard to find out where you were if you forget.
1 set = 1 sc and 1 ch.
Attach red yarn to the edge of the wrist warmer, in the middle of the yellow section.
1: Distribute 18 sets around the edge of the wrist warmer. (More if you made more rows before)
2-6: 18 sets
7: Left handwarmer: 8 ch, skip 8 st, 14 sets. Right handwarmer: 14 sets, 8 ch, skip 8 stitches. (You might have to this part a little differently, but the important part is that you make a gap of 8 stitches somewhere on row 7 so you can put your thumb through there)
8-12: 18 sets
Switch to yellow yarn and make slip stitches in every stitch around the edge. Attach all loose ends.
Use blue yarn and make a loop.
1: 6 sc in loop
2: 2 ch, 2 dc in every st, sl st in first dc.
Switch to yellow yarn.
3: 2 sc in every st, sl st in first sc.
Fasten off, leave a long end and stitch the repulsor to the glove.
