Ok. I needed to figure out how to make the mitts heat resistant.
I tried felting hot spots but the mitts are still not heat proof. I tried to add puffs of roving inside the mitt, but there seems to be hot spots, although I LOVE the feel and look. They would make better mitts than oven mitts.
Adding cotton quilting worked inside, but they didn’t feel as good as the lovely little merino sweater mitts.
