This project was something I've wanted to try for a while. I really wanted to do something like this as dessert trays for my wedding. The few times I went to the thrift store last spring I wasn't able to find the right plate or I couldn't find a candle holder that was heavy enough. By chance, a couple months ago, I found two silver candle holders with a nice base and some decent weight to them. Not too far away, on the same shelf, I found matching China with a pretty blue flower pattern.
I used my hot glue gun on high heat for this project. The truth is I had a "win" and a "fail". I was able to get one of the plates to stick to the candle holder and maintain a grip. The other one wouldn't no matter how many times I tried. (Good thing about hot glue is if it won't stick it's pretty easy to peel off.)
I'm not really sure what the solution is... possibly gorilla glue? or super glue? If I ever find the time I'll try it again. If this project interests you there are lots of other "pins" on Pinterest that might be able to provide additional insight.
