Pull gently to the right length Now make the piece that you are working with longer and looser: run it through your hands and pull it gently bit by bit in the lengthwise direction, but so that the piece still remains intact.
Pull the loosened string into three equal pieces. Do the following with each of the pieces: pull the piece loose in the middle, in the lengthwise direction 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. Keep repeating this action until the Wool Crepe is transparent.
Hold the Wool Crepe against the light to see if there are any dark patches.
