[QUOTE=Tony;44470]That depends on what kind of frogs you plan to keep in it, but if you do replace the screen with glass I would use double strength (1/8"), 1/4" is overkill.

Thanks for all of the good advice, Tony. 1/8" glass it is. If I can get this at Lowe's I might be able to cut it myself (I think I have one of those glass cutting kits around here someplace). But how do you seam the edges to get them smooth?
