Preparation and Safety Guidelines

Tools Needed

  • Scrap muslin or fabric
  • Scissors

Safety Guidelines
  • Wonder Under is heat-activated adhesive; always use caution near heat sources like irons. Test a small area first to ensure it won't damage your fabric.
  • Ensure your iron is at the correct temperature for your fabric type. Too much heat can scorch or melt fabrics, while too little may not activate the adhesive properly.
  • Always use a pressing cloth or parchment paper between your iron and the fabric to prevent adhesive residue from sticking to your iron and to protect the fabric's surface.

Common Mistakes to Avoid

1. Uneven Fabric Placement

Reason: Improper alignment of fabric pieces before fusing with Wonder Under can lead to wonky blocks.
Solution: Carefully align fabric pieces using a ruler and pins before applying heat.

2. Insufficient Iron Pressure/Time

Reason: Not applying enough heat and pressure for a sufficient duration can result in the Wonder Under not adhering properly, leading to loose fabric pieces.
Solution: Use firm pressure and a hot iron for the recommended time to ensure complete adhesion.

3. Choosing the Wrong Fabric

Reason: Using fabrics that are too thick, too stretchy, or with loose weaves can hinder the effectiveness of Wonder Under.
Solution: Select lightweight to medium-weight fabrics with a tight weave for optimal results.

FAQs

Can I use Wonder Under on all types of fabric?
While Wonder Under works well on many fabrics, it adheres best to natural fibers like cotton and linen. It may not work as effectively on very stretchy fabrics or synthetics like polyester. Always test a small, inconspicuous area of your fabric before applying Wonder Under to the entire piece.
