When you knit you often end up with bits of differents yarns. I like to use those bits to other projects, like for instance wrist warmers. These ones are super easy to do.
The yarn is what was left from the pink sweater I knitted for my daughter and is of 65 % wool and 35 % alpaca.
I knitted on regular knitting needles, *4 rows knit stockinette, and on the 5th row purl and continue with stockinette för 4 rows* (*repeat), so you end up with a rib looking pattern. Knit to desired size to fit your wrist. Sew the sides together.
