Unless you’re using silicone protective paper, blowout paper should only be used once as once the stray ink from the previous project gets reheated, it can get on the current project and ruin your design. If you’re environmentally minded and looking for a way to reuse blowout paper, you can use it for kids’ crafts that don’t involve heat, or use it to protect tables or floors during art projects. You can also shred used blowout paper and use it as packing material.
