These Crochet Pot Holders are made using two separate strands of yarn, so they are double thick to protect your hands. They are a large, 8 x 8 inches and made from 100% Cotton - they will not melt like Synthetic Yarns will. These are perfect for your cast iron and everything else. I have used these for years - I use what I make and I love them - as I am sure you will. They will last for years and are easy to clean, just toss them in the washer with your towels and lay flat to dry.
