It's time to make gifts for Christmas and one of the best is a set of bowl cozies. These 100% cotton wonders cradle a bowl in the microwave, saving fingers from trying to handle the hot contents after heating is finished. They are quick to make. Fabric choice can make them bright and cheerful. Various sizes are easy to make.
The key is everything must be 100% cotton: the fabric, the batting and, yes, even the thread. This will avoid potential fire hazards or sparking in the microwave.
