My latest shopping nightmare has been trying to find 12x12" or 4x4" photo frames that are already backlit or that I can easily backlight so I can put etched mirrors (or etched acrylic or glass) and have it look SUPER COOL. I feel sure that these things exist somewhere but trying to search the current web marketplaces (amazon, ali*, etc) is super frustrating.
I know there are online stores that specialize in laser blanks and supplies but it seemed they were all targeted for bulk commercial customers, not hobbyists like me. Amazon is where I get most of my stuff.
