Holy shit! Haha the SMALL ones a7 (3x4 inches) are $30 each! Ouch... Maybe I'll go for a less clean look... :/

You learn quickly grasshoppa.

I've made my own cheaply and easily in the past, by printing up (white) Avery Labels in a number of sizes, then sticking them to similarly sized rectangles of (white) 8-ply mounting board, giving them a clean, raised appearance, for everything from wall identification to prose. Applied to the wall with self stick velcro or those temporary gummy adhesives, they may easily be changed out. I've never had any comment about them other than that they were assumed to be professionally made.
