Cardboard Loom Woven Mug Cozy Instructions ♥️ Here's a more detailed tutorial for weaving a mug cozy on a cardboard loom. I used a tape measure to find the circumference around my mug and used that as the length for the cardboard loom. Once you are finished weaving, you can pull the cloth right off the loom. No need to tie the ends since everything is looped together! #kidcrafts #easycrafts #valentinesdaycraft #diyvalentine #diygift | Diy Concept
