A great marking tool, especially for transferring embroidery patterns onto natural textiles, such as cotton and linen. The screw-out red cartridge is first used to transfer embroidery patterns onto transparent paper. To ensure the pattern is displayed correctly, use the iron-on pattern pen to clearly trace it on the reverse side of the transparent paper. Finally, the embroidery pattern can be ironed on with gentle pressure. Once the embroidery is finished, the pattern can be washed out with ease. A cute addition to anyone's sewing basket.
