I have made a lot of those and I have a pattern that I developed and they are very easy to make. I use a double sided prequilted fabric and you cna use any thing that is thick like a denim or some such fabric wiht batting or insulbrite in it. I used bias binding on mine. I sold a set of them for $12.00 a few uears ago. Yours looks nice nad they are great for cooking in cast iron skillets. I have one on my big skillet that is sitting on the stove. I call them panhandlers. Have a great day Huggies, Fay
