Sewing, embroidery, patchwork, quilting, appliqué work – whenever temporary markings on fabric need to be visible, Prym's THERMO-Trick Markers are practical. These heat-erasable markers draw fine lines on a wide variety of textiles. They are also ideal for stencil work where precise marking is essential. The Prym set contains two heat-soluble markers, one with a white and one with a blue tip: This makes the lines clearly visible on both light and dark fabrics. How do you remove the marker from the fabric? An iron is all you need. The lines of the heat-soluble fabric markers can be easily removed by ironing without steam. Simply set the appropriate temperature for the fabric type and use a pressing cloth for delicate fabrics. The markings disappear as if by magic. Small marking mistakes can also be quickly corrected with the integrated eraser. Alternatively, the fabric can be machine or hand washed. A few practical tips: Please store the marker vertically with the cap facing down to prevent it from drying out. Before you begin, we recommend doing a small test on an inconspicuous area. Every fabric reacts differently. If marks reappear—which can happen at temperatures below 0°C—they can simply be ironed away.
