Everyone hates getting snow up their coat sleeve when they need to scrape away the nights snow. This mitt fits over your ice scraper and keeps your hand nice and toasty, no need for gloves. This project works up super fast with bulky yarn, cast on and you can have one ready for the next day’s snow!

This pattern uses the Magic Loop Technique.

Needles: Size 9 (5.5 mm): 32” or longer circular
