The first time I tried to use heat and bond, I did not read the directions (stupid, I know... :oops: ) That lesson cost me a new iron and ironing board cover. I was at least smart enough to buy a teflon sheet for all future projects. I don't think I would use iron-on products at all, had I not found out about 'teflon pressing sheets' from my LQS. I heartily recommend them. I couldn't get all the goo off my iron. I will be watching this post for answers. Thank you for asking the question. :D
