Our school enjoyed having them hang in the cafeteria. They are now stored away as we will have a special expo at the shopping mall at the end of January and some will be shown again at the Pump House art gallery when Aquinas Schools has their elementary show.
The stacked colors really look marvelous in all of the student work. I think either the rectangle or the oval worked well for background fills. I prefer the oval, but it is a bit more work to make all these shapes. The students were aware of stacking the paper to cut more than one layer at a time.
