Here you can see a concept photo using some scrap wood to frame the door way. https://www.dropbox.com/s/l63v5f80mlgn4cl/TilesDoorwayConcept.jpeg?dl=0
I've found some nice white PVC 1x6 boards that will better serve in an outdoor application. Now I'm thinking about how to attach the tiles. https://www.dropbox.com/s/pywjh6oc7x8ctdb/TilesOnWhite.jpeg?dl=0
Part of me wants the ability to rearrange them at whim , but that's got so many issues wrapped up in it, not the least of which is irregular sizes.
Plastic to plastic bonding is pretty challenging so i don't adhesives will be the answer.
i'm leaning towards some kind of tiny hook and eye rig but haven't actually tried anytthing yet.
for the time being, i've got the tiles laid out on the patio and i'm enjoying the looking and rearranging and looking and rearranging.
