As a once upon a time visual arts educator, I cannot shake the habit of collecting useable materials that are perfect for projects. Right now, I have about 25 foil lined 1 cardboard 1lb coffee containers with lids and many many toilet tissue rolls. The coffee containers have been used for pinhole cameras, storage containers, building blocks or bowling ‘pins,’ etc. etc. The TP tubes are good for many things!! If you are interested, they are free for the taking- just let me know and I will leave them on my porch.
