Looking for a quick crochet project? This Crochet Mug Rug is a super easy and quick make. Small crochet projects like these mug rugs make perfect last minute gifts! It uses very little yarn and you can use up your leftover yarn from previous projects. I used cotton yarn, worsted medium weight (4). But you can use any type and thickness of yarn you like. All you need for this project is some yarn in two contrasting colours, crochet hook and scissors.
