I'm on the net surfing the web for a casserole carrier and came across this one. I understand the two D rings. However, the strap is how wide? It looks like it is about 2" or 21/2" wide? I take it that the strap is sewed down at corners and of course the length is longer! I need to make one of these. I have the material and insul-bright stuff. will be looking for response from you or anyone else. I'm new to the site so hopefully I'm doing this right.
