The seven pieces in the second photo are all the same size, approximately 45cm x 85cm. They were fabric sample swatches and have three holes on each end. The single piece in the third photo is 40cm x 80cm. I'm not sure of the exact fabric material, but it's a smooth, synthetic fiber. These were found in my family's storage shed, but I'm not good at sewing, so I can't use them. If anyone can make good use of them, such as for patchwork, please do!
