I have a couple leather ones I bought and over time it did shrink...(see photo below) It was not lined but pretty thick and sewn. I bought some printed leather and wanted to make a few myself. It is thinner leather so I plan to hand sew it and was looking for something to hold it in place while I sewed it together. That's where I read about rubber cement but was concerned about the heat element. I typically leave the pot hold on my cast iron, because I often move or hold my pan as I cook...but make sure the top of it doesn't touch the main part of the skillet.
