You have to use all cotton when making these since polyester will melt in the microwave, so I used cotton fabric, all cotton batting, and cotton thread. The pattern is fairly simple but the prep work before sewing them is tedious. I found the pattern here.
There are a lot of patterns out there but I liked Lisa's the best.
Since our Guild Quilt Show is coming up next week I decided to make some for the craft table at the show to sell.
You can see the inside more than the outside but the outside is pottery bowls.
I made three of these for the guild.
