I thought I would go ahead and post a photo of what we did for our Valentine sacks in my classroom last week. I had a bunch of white paper bags and decided to let the children marble paint one side of them with valentine colors. They turned out very pretty. I didn't take a photo of how I set it up for them to do, however, just a photo of the finished bags hanging on our drying rack. However, we used a process very similar to what we did for our spider web paintings back in October. This time, I just used three colors and three marbles instead of only one. The children used these bags to take home the valentines given to them by their classmates.
