Having just typed that, I heard a crack and I have broke another glass plate. Not to worry, they are really cheap. 
Wow, I still haven’t cracked one. Ikea quality 
Hmm, might have to send my wife to Ikea. Yet again that could cost me more than a few photo frames…
Likely I usually go with my wife to keep things under control. Not sure if it helps.
I always end up walking around looking for things to harvest/repurpose for hobby projects. Actually, that pretty much sums me up in all kind of shopping related situations.
