Love your cozy. I made many for family and friends. Wouldn’t have given them away until I tried them in the microwave myself. I Ordered 10 yards of wrapnzap on line. Then being I knit and crochet I decided to crochet one with 100% cotton yarn. Haven’t made a fabric one since. they work up quickly and give me something to do at night or during Packer football games. Go Pack! These can be folded and tucked in a drawer. I’ve tried several ways to launder them and all worked. Took them out of washer and dried over inverted bowl, or stretched them back into shape and pinned from 2 corners on a hanger and unintentionally dried with towels. Thought I ruined it but alas I I just pulled it back into shape and it was good as new. Found the pattern on Pinterest.
