Gel fabric marking pens for light-coloured fabrics with marks that erase by rubbing with the built-in eraser or by applying a warm dry iron. Non-toxic ink lays a fine 0.7 mm line for pattern transfers, quilting grids and cutting guides, offering a clean alternative to chalk. Test on a fabric scrap to confirm removability and avoid heat-sensitive finishes. Follow basic usage guidance and test on a scrap when applicable.
