INVISIBLE 'CLEAR' REPAIR material, it is made of 100% proplyeenoxide. LINK ABOVE is a tutorial video for the hemline repair which has a paper backing where you can directly iron on. The paper is then lifted out of the way and replaced with a fabric match/swatch then ironed on again to complete the repair as the video shows.
The Invisible Mending Tape is ideal for repairing holes in fabric trims, attachings motifs, and hot-setting iron-on patches.
