Polyfuse Paper - Matilda's Own
Matilda’s Own Polyfuse 5 x A4 Sheets
Polyfuse is a fusible water soluble tearaway. It softens when washed and does not leave any bulk to your design but leaves a think layer of polyester fiber which helps reduce shadowing in applique and pads the shape.
Polyfuse Water Soluble Tear Away is equivalent to Stitch n Wash.
