Canvas with heat activated adhesive. This is perfect for backing shoe upper panels, or even parts of fine leather projects where you need a little extra support.  

Size: 1 Yard ~54x36"

Directions:

• Cut canvas reinforcement to size, slightly smaller than the piece you are reinforcing.
• Peel backing to expose adhesive.
• Take care not to let freshly exposed adhesive touch itself.   In some cases it can stick to itself although the adhesive in this state is relatively weak.  If left out for a while it is less of an issue.
• Apply to material.
• Manufacturer recommends pressing at 240F for 5 seconds.  You can still make this work with a regular iron, Cricut EasyPress, etc.
