Effortlessly transfer your embroidery designs with the Prym Iron-On Pen, specially developed for use on natural fabrics like cotton and linen. Ideal for beginners and seasoned stitchers alike, this washable marking pen makes pattern setup simple and accurate. Just trace your design onto transparent paper, flip it for a mirrored image, and then iron it onto your fabric. The ink gives you a clear guide to stitch along, and once your embroidery is complete, the markings wash away easily, leaving only your finished artwork. Please note, this pen is best suited for absorbent, natural fibres and should be tested on a fabric scrap before use.
