Last year, we spent some time decorating our sliding glass door with pretty leaves that we cut out of watercolored coffee filters. Since we were in the process of moving, we had to remove our leaves soon after putting them up. I knew that the pretty stained-glass effect that the leaves had in our old house would be wonderful in our current playroom. We took our time with this project and painted our coffee filters one night just before bathtime. The next day, I made two leaf tracers on card stock and Sugar Plum and Little Man traced the leaves on to coffee filters that I had folded into fourths. I then cut the leaves out and we took turns applying a tiny bit of glue stick glue to the backs and sticking them on the window. When it is time to take our pretty leaves down, I will just peel off the leaf and spray the window with glass cleaner to remove any glue residue. Then we'll do it all over again with snowflakes!
