I absolutely love knit slipper patterns, but sometimes they don't give me enough coverage - what about ankles? Those need to stay warm, too. If you've found yourself in the same boat, I invite you to try knitting up a pair of these incredibly cozy Cranberry Slipper Boots. Big enough to slide on over a pair of socks, these toasty slippers are worked flat with short rows shaping the top of the foot. Best of all, they go all the way up to the ankles for an additional layer of warmth.
