Yesterday, I showed you Paula's hat. Here is the neck warmer I devised to go with it.
To make, cast on 25 stitches and knit in garter stitch for 63 ridges, then cast off. Roughly fold in half, tie through four layers with a length of ribbon (about 1"x 2" from edge). Trim the ends of the ribbon and seal the ends with glue.
The neck warmer easily stretches to fit over my head without having to untie the ribbon.
