Unless otherwise noted, they are made from little paper mache book-shaped boxes about 2.5 inches tall by 2 inches wide.
This started as an accident. I had glued some paper to the cover and didn't like it so I tore it off. Then I tried to paint it and realized that layers of the paper mache had come off with the paper. I went ahead and just stained it instead. Then I realized that between the peeling off of the paper and the moisture from the glue and stain, the cover was starting to tear off. I set it aside and the next day at work came up with the idea of stitching the cover on...and there you have it.
