This bag is actually designed to be a camera bag. This one was a surprise from my wonderful daughter for Christmas last year. It's from Jo Totes - http://www.jototes.com/ . There are others on the market as well.
It's interesting that some shops still advise stitchers to basketweave belts with wool hinting that that's the only thing will hold up. I don't agree. Modern-day finishers can do amazing work that will hold up and withstand the test of time - their techniques and products are much more advanced these days. Why, just look at this one! I say stitch whatever you want with fun threads...life's too short to have a boring strap or belt! Of course, that's just my opinion and I guess we'll see how mine holds up. I used everthing from fyreworks to velvet in this one and it turned out really cute! I have another belt canvas in progress that will be made into a camera strap. I seem to have stalled out on that one a little bit.
