Question re: 100% cotton fabric
I have fabric that I've had for a while and want to use for microwave potholders. The fabric is not marked 100% cotton and heaven only knows where I got it. it looks and feels like quilting cotton. I used a pyrex cup with water in it, draped the fabric over the cup and "cooked" it in the microwave for 60 seconds. No sparks, no melted fabric. This should be safe to use, right?
Thanks
