A neat, different type of slipper pattern fitting both men and women. Uses double strands of worsted weight yarn, so work goes quickly, and slipper wears better! What a fun project to do! Make lots of these for last minute gifts for your friends too! Very toasty warm , good for colder climates and winter wear, but comfortable to wear all year round. Knitting needles, US # 9 and # 11. Fast and Fun!
