Thanks, cool that you are going to try rivets for the straps. I look forward to seeing that, bet it looks really good! It is about the thickness of quilting cotton, maybe just a tad thicker, but seems like it is a blend, has a bit of shine to it, a little slickness, if that makes any sense. Sort of like the material that my cloth shower curtains are made of, if that helps. I got it at Walmart in the clearance bin for 1.50 a yard, and didn't think to notice the kind of material it was. I think the bag will probably hold up very well. It holds its shape when empty, I used fusible heavy weight interfacing on each piece, so it made it pretty sturdy. I won't find out how it will hold up to being used until vacation time, though. I couldn't get my husband to understand why we need to take a weekend away to test out my new bag, lol!
Thanks for the link, and info for purse supplies. I will look into that.
