Fusible interfacing is an indispensable tool in sewing, quilting, and various craft projects, offering a way to enhance fabric with additional support, structure, or durability. Understanding what fusible interfacing is and how to use it effectively can significantly improve the quality and finish of your sewing projects.
What is fusible interfacing?
- Definition: Fusible interfacing is a fabric layer that’s applied to the wrong side of another fabric to provide extra support or structure. It has an adhesive on one side that bonds with fabric when heat is applied.
- Variety: Comes in various weights and structures, compatible with a wide range of fabric types.
- Applications: Used to stiffen or add body to fabric, such as in collars, cuffs, and facings in garments, or in parts of quilting projects.
How to Use Fusible Interfacing
- Identify the Fusible Side: The fusible side is typically rougher due to the adhesive. This side goes against the wrong side (non-visible side) of your fabric.
- Pre-Wash Fabrics: Pre-wash both your fabric and interfacing (if necessary) to prevent shrinkage after application.
- Cut to Size: Cut the interfacing to the size and shape needed for your project.
- Position Correctly: Place the interfacing on the wrong side of your fabric, ensuring the adhesive side is facing down.
- Use a Pressing Cloth: Lay a pressing cloth over the interfacing to protect your fabric and iron.
- Iron Carefully: Follow the manufacturer’s instructions for temperature and duration when applying the iron. Use a pressing motion rather than gliding the iron.
- Cool Down: Allow the fabric to cool and set before moving it. This ensures a strong bond.
