Saw a discussion of how to carry things when running/traveling etc. I have some very stretchy fabric and decided to make a loop with some holes in it for charge cards and passport. I just used a 7.5" inch tall fabric with the width of my waist. I purposely opened the passport part slightly to show whats in it. I didn't use a zipper because the fabric is so stretchy that I left an opening about 1/2" narrower than the passport so it can't fall out.
