Towel Tote/Beach Bag
For the interior, I used a thrifted faux suede in a burgundy color. It was in pieces, so I patched it together (who's gonna know?). If I really were using this as a beach tote, nylon would be a better choice for wet swimsuits, etc.
For the pocket, I took a washcloth I bought at the Japanese store, and folded it in half. The top edge was already finished, so it makes a self-lined pocket that matches beautifully. I added a velcro closure.
I was looking around for other tote patterns using towels, and found quite a few.
here's a nice one by Martha Stewart.
