I bought mdf hardboard. This stuff was like $5 for a large sheet. I painted the whole board with 4 layers of magnet paint, and 2 layers of white paint. I cut them down to the same size as the empty frame I had. Then I used tiny nails to hold it in place.
I have mine just leaning against the wall for the girls to play with. I am going to cut out more images. The cute purses and all the outfits and probably a couple more girls. They are so cute. Do you spot that little green bow in her hair? That is the inspiration for my project tomorrow.
