Mandala/kaleidoscope
Coffee filter mandala/kaleidoscopes have endless possibilities. I haven't counted how many of these I have created but I bet in the hundreds. Coffee filters are cheap and very durable. They are obviously not indestructible but they will take some stitching. Markers and paint are not a problem at all. There are many ways to take them further but do I have to? What if I make them just for the pleasure of making? Period, end of the sentence.
