I'm not sure about the material, but it might be wool. Knit fabric. It's a lovely fabric. It's not thick. It's thinner than felt, but it's not see-through. A very beautiful blue color. It's somewhere between blue and navy. It's a little darker than in the image. It's been used and cut, so the scraps are still attached. Usable rectangular area size: 146cm x 135cm There may be some error. The scraps are also usable for small items. They are not tiny pieces. Handmade For stoles, dresses, skirts, and pants, etc.
