This is my second attempt at posting this question, so it's shorter than the first.
I am making an oven glove from the Cath Kidston book "Sew". It says to use cotton batting, would it be ok to use man-made wadding as I already have this at home? Would wadding be as effective against heat?
I would use cotton. The manmade batting will melt if it touches the grill elements etc., the cotton will just scorch. (I have made oven gloves in the past and managed to burn small holes round the edges!)
