For Fusible Applique, simply place the applique design under the Appliqué Fusing mat. The cut applique shapes can be placed perfectly since this mat is transparent. Because this mat is heat resistant, hence multiple layers can be placed simultaneously while pressing it with a hot iron. The layered appliques can then be picked up as one piece and placed on the background fabric. The mat is slightly tacky so the pieces won’t migrate when positioned. Since it can withstand temperatures for up to 500 degrees F. (260 degrees C.), hence it is the perfect working surface whenever using a glue gun. Any globs of glue will flake off easily and protect the table underneath. It is very easy to clean. Just wash the mat with soap and water or place it in the dishwasher and you're good to go!

This Appliqué Fusing Mat is made of silicone and glass fiber material that is heat resistant for up to 500 degrees F (260 degrees C.).
