carbon transfer paper
This is carbon paper by Hemline, for transferring marks onto fabric, such as embroidery patterns. On a hard surface, lay a sheet of carbon paper onto your fabric, put your design over the top and then trace around to transfer the pattern onto the fabric.
You will get 5 sheets - 1 blue, 1 red, 1 yellow and 2 white.
Always test on a scrap of fabric first!
