They can draw on the paper bag while it is flat. They can add color with watercolor paints, but I urged them not to get the paint too watery. As usual, a sample project by me was an inspiration for lots of their own enchanting and individual ideas, as you can see.
We had some white paper ready for them to make a roof, folded in half, so they could cut both sides of icicles at the same time. We helped them size their roofs so that details on the houses wouldn't be covered up. We wanted them to glue the roof on top but a few children found the stapler and used that.
