General Directions:

  1. Pin pattern piece to Shape-Flex following grainline arrows and cut. Trim seam allowances to 1/8". Please fusible side of Shape-Flex against wrong side of fabric. Pin, then steam-baste along edges with tip of iron. Remove pins. 
  2. Cover with thin, damp press cloth. With iron at Wool/Steam setting, press firmly for 10-15 seconds. Repeat, lifting and slightly overlapping iron until all interfacing is fused. Steam press on right side. Let fabric cool, then check bond. 


  • Use the damp press cloth as a temperature and timing guide. After 10-15 seconds, press cloth should be dry. If not, raise iron temperature or hold iron in place a few seconds longer. 
  • Use steam iron with metal sole plate. Hand-held steamers wil not permanently bond interfacing to fabric.
  • To pre-wash, soak in warm water for about 10 minutes. Gently squeeze out the excess water and line dry. Do not put in a washing machine or dryer to pre-shrink as that may dislodge the fusible.
