With the transfer screen Prym offers a practical tracing film, which can be used to transfer motif and graph templates to the fabric in two easy steps . First place the 25 cm x 45 cm transfer screen on the selected motif, in order to transfer the design onto the film using any marking pen. In the second step place the transfer film on the fabric and trace the motif. The pattern appears on the fabric as dotted lines through the fine perforations of the transfer screen. If a washable marking pen is used the transfer aid can be used a number of times.
