Because they are made of cotton, these are great coasters! You could use acrylic, it would definitely still give that rug look, but acrylic yarn won't absorb moisture as the cotton yarn will.

This coaster is a must-have right after the cup cozy! This quick and easy free crochet pattern is perfect for beginners and designed for all the coffee lovers in your life.
