I always look for inexpencive ways to decorate my home..when I saw those treys I had to get them and do something with them. They are in 3 different sizes, 18x14cm, 22x18cm and 26x22cm. They were already painted white, all i did is I added some different papers and embelished each one in a different way. I kept them in the same style since I knew I want to hang them all close to eachother. It was a very inexpencive project but turned out very nice.
