Debbie: I love the looks of the one in your photo too ... and immediately thought about slate. What a great idea of gluing it to a terra cotta pot!
Clint: Look forward to photo's of your latest project!
I'm not very creative or crafty ( and I'm impatient as well), so I'd much rather purchase these already made than have to go through the mess of glue etc. and trying to make them myself.
