There are 5 sheets in the set - blue, yellow, red, green and white.
We have tried: Through this copy paper, we tried to transfer a line of cuts and seams on various materials, such as cotton, polar fleece, satin. We drew lightly. We cut the copied parts in the marked lines and sewed the seams behind the marked seam line. We washed the sewn products to the recommended temperature, the marked lines and marks disappeared.
