Pull gently to the right length
Now make the pieces that you are working with longer and looser: run them through your hands and pull them gently bit by bit in the lengthwise direction, but so that the pieces still remain intact.
Make 2 flat pieces
Carry out the following actions twice: pull the loosened piece into two in the middle, in the lengthwise direction along with the hairs; then place the two pieces on top of each other and divide them into two again. Keep the hands about 20 cm apart.
Hold the Wool Crepe against the light to see if there are any dark patches.
Keep repeating this action until the Wool Crepe is transparent. The pieces get increasingly shorter and thicker.
