Now I'm confused. I thought Warm & Natural was all cotton. I just made sev. microwave bowls using it & have taught sev. other people how to make them using W&N, too.
I am worried now though so I just ck'd the thread I used & it's Coats & Clark which I've used for yrs. but now I see it's polyester covered polyester.
I now use the threads from Connecting Threads.
