Iron-on pattern pencil, water erasableThe washable iron on pattern pen from Prym is a suitable marking tool, especially for transferring embroidery patterns onto natural textiles, such as cotton and linen. The screw out red cartridge is first of all used to transfer embroidery patterns and motifs onto transparent paper. To ensure that the motif is displayed the correct way round, the motif is once more clearly traced on the reverse of the transparent paper with the iron on pattern pen.
