I made an elasticated darkcloth for my 4x5 camera then realised all I'm doing is making a simple skirt with an elasticated waistband. It's incredibly simple to sew and fast if you have a sewing machine available to you. Just need to decide on a cloth that is right for you. I'd go for a black cotton drill fabric.
Your're right, it is just a skirt and rather easy to make. Just don't have a sewing machine. Thanks for the reponse.
