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.
Thanks for the advice about the brads, I ended up having to use large snaps instead. I just used the top part, and they seem to work fine. I also used some on the handles, to secure them at the top. It adds a nice decorative touch, I think(maybe that will draw the eye away from the supporting stitching, lol). I also made the handles a little longer, I think. Here are a couple more pictures, finished, showing the snaps I used. It's not perfect, but it's good enough for me! I am planning on making another soon for my daughter for our next vacation! Thanks for looking!
