Evidently her friend Forest purchased a bunch of these small Rocky Mountain National Park panels based on vintage park posters and pictures. They ranged from about 3x3 to 5x7 inches. Barb had more than she had stuff to do with so she kindly sent some to me!
I'm a big national park fan, I hope someday to visit them all, but I've not yet been to Rocky Mountain. Initially I wasn't sure what to do with the panels since they were so small, but after looking at them for a while I decided the vintage styling would be great as a mid-century inspired handbag.
I'd purchased some wooden purse handles online a while back with no particular project in mind, but figured this would be a great chance to use them. I sketched several different shapes, but the maximum size was limited by the panels. I wound up piecing them together and adjusting my pattern a bit as I went to be able to fit the panels.
The exterior is interfaced with automotive headliner fabric and the lining is interfaced with sf101. I put only a single zip pocket inside and a magnetic closure, so it's a fairly simple bag.
