This isn't much of a before and after, but I'm pleased with how it turned out. We got this china cabinet last summer on Craigslist, along with a matching buffet.
The hutch part of the china cabinet had gold painted diamonds on the glass (you can kinda see that in the picture above). I tried getting it off (I discovered that nail polish remover would get it off, but it was taking forever) when I finally decided to just get new glass for it. I didn't feel like nailing the trim holding the original glass back into the cabinet, so I hot glued the pieces in. Worked like a charm. My 2 year old came over and started hitting the glass while I was finishing up one of the sides. My head was in the hutch and he thought it was a fun game. The glass didn't budge, so I think hot glue was a wonderful, quick solution - and so does my husband. He'd been a little skeptical.
Here it is with the new glass and my china out of their boxes for the first time in 15 years! I haven't gotten around to making it look cute yet. That'll come after I know my boys aren't likely to want to touch/hold anything in the cabinet. I already told my hubby that now that we have the storage space, I'll be on the look out for some nice crystal goblets at the thrift store, too.
