So I had wanted to make a couple of fleece tube for my chins. I went out got all things necessary and was ready to start until I found out there are several types of fleece. I have fleece now and I don't eve know what kind it is...the store I went to was a mom and pop shop that's been around for ages, so nothings really orderly. I got the fleece from a section that said polar fleece. It looks like normal fleece to me. How do I know if what I got is safe to use? It's not the slippery fuzzy kind. Also I did wash it and dried it and it didn't form any balls, but it may take more than just one wash to see if it does. What should I do?
