This paper provides a protective sheet between your plastic beads and your iron, but will still ensure that you can fuse your beads together to reveal your designs. To use simply place the beads on your pegboard to create your design and once you're all set place a sheet of ironing paper over the beads and use your iron to set the design. The heat of the iron will fuse the beads together and you will have a perfect creation! Pack of 40.
