Protip: While knitting, it doesn’t matter what end is “middle top” or “middle bottom”. Stitch count and length are exactly the same. Just do the right slipper x2 and stack the flaps opposite each other.

I have a vest in this yarn and it is ridiculously warm. If I wear it with a long-sleeved tee, I feel toasty when it’s almost freezing outside. I call it my tummy oven. These are for my feet, to combat the bizarre sudden freeze they suffer from the moment I get in bed.

Leg - 22 ridges
Top flap - 10 ridges
Bottom flap - 6 ridges
Foot - 18 rounds of ribbing before decreases
