DIY Bead Stair Tray

J-jo doesn't like things rolling around. He was extremely bothered by the above work. To decrease J-jo's frustration with the bead stair without spending a penny, I browsed through my stores of craft material for inspiration and came up with this:

 Lay out your bead stair on top of the craft foam and trace around the triangle.  With an exacto knife, cut out the traced triangle.  Glue that piece of foam (the one with the triangle cut out) on top of another two pieces of craft foam and voila, a bead stair tray. End of frustration.
