I had two white cake plates for a while that I wanted to make a set by adding a smaller plate to the top. I found this saucer for 50 cents a while back but wasn't crazy about the candle holder I found to go with it. Finally, I found what I was looking for (at the thrift store for 50 cents) and dabbed a little E6000 on it, stuck 'em together and:
Now I have a complete set of cake plates. The bottom cake plate, I received as a shower gift. The middle I bought from a store that was going out of business for $6. The one I made only cost $1, so now I have a set of 3 cake plates for under 10 bucks! Woot!
