Copy paper, including note blocks

Related posts: Fading colors — degradation of paper over time

Copy paper (also known as printer paper) is easily available and inexpensive. I don’t use it much for tessellations or figurative models since its folding properties and looks are far from perfect, but I do find it very well suited for many kinds of modular origami and for test folds. The most convenient form is note blocks which contain small pre-cut squares, usually with a side length of 8-9 cm. Be careful, though, as quality differs: some brands use precisely cut squares, some don’t. Paper quality differs a lot as well. In Poland, what is sold in stationery or office supply stores under the name “origami paper” (papier do origami), is almost always somewhat thinner copy paper rather than the kami paper you might expect.

Ilan Garibi has published a detailed printer paper review which is worth reading, and I wrote down my observations about aging of copy paper.
