I made a drawstring bag to play with this a little. It is probably a little bit of stretch for this technique but, it worked out pretty well. I have another idea for something that is probably better suited to this approach.
I put a very simple little Celtic key pattern motif in the center of each tile to give it a little more visual interest, then leaned in to the “key” theme with a key pattern wreath on the bottom and, modeling and 3D printing a couple of keys to use as toggles.
Here is an SVG of the plain tile adapted to the JPP Saddle Collection faux leather, in case someone else wants to play with it.
