The Shamrock Crochet Coaster Pattern has been so successful I thought I would create a post telling you how to take the same pattern and make a shamrock crochet potholder. And also, we will be using the same yarn weight as before. Sounds impossible? It’s actually quite simple and fun. Keep reading for a video on how to do this. While the three leaves of a shamrock stand for faith, hope, and love, the fourth leaf is luck. I hope luck finds you, and this crochet coaster is a reminder to appreciate all the luck that comes your way.
