The key to happy knitting is for the journey to be as important to you as the destination.

It employs mosaic knitting, so the slipped stitches make it double layered. So it is very warm.

Mosaic knitting colorwork is very easy.

I recommend that you use two colors of yarn that have a lot of contrast. Two solids, or one solid and a variegate/tonal work wonderfully. Just make sure they have a great deal of contrast.
