Patterned papers are essential for origami models, especially if they are modular. They can add that little extra that makes the difference between "nice" and "wow".
This small checkered pattern is sometimes part of japanese paper packs. I never could find out how it is called. However it is made here with the intention to give you two colours on one sheet. Cutting into fourth you will end up with 2 turquoise and 2 copper sheets. That might be helpful for Kusudamas. Or you divide into thirs and get three patterns. One is a smaller copy of the original, 4 are half turquoise, half copper. and 4 more will have solid colours. I find the striped ones helpful for colour change where that is usually not possible otherwise.
32 sheets per package is just enough for a standard kusudama with two papers spare to practice and experiment. The paper can also cut into four. Most kusudama artists actually prefer the 7.5×7.5 cm format over the big 15×15 cm. In fact you can quadruple the number of kusudamas if you go the extra mile of cutting the paper. The thinness of the paper guarantees that the paper is still thin enough for precise folding.
