Tips for Using Bonded Fusible Interfacing

How to Get the Best Results with Bonded Fusible Interfacing

Bonded fusible interfacing is used to add structure and durability to your sewing projects. Whether you're reinforcing a collar, stabilizing a quilt block, or giving your handmade bag a little extra body, here are some top tips for working with this essential sewing supply.

1. Choose the Right Weight
Bonded fusible interfacing comes in different weights, from lightweight for delicate fabrics to heavy-duty for structured projects. Always match your interfacing weight to your fabric for the best results.

2. Use the Right Heat & Pressure
To fuse properly, place the interfacing with the adhesive side down onto the fabric. Use a dry iron (no steam!) and hold it in place for 10–15 seconds. Move the iron in sections rather than sliding it to ensure even bonding.

3. Test Before You Press
Before fusing onto your final fabric, do a small test on a scrap piece. This ensures the temperature and timing are just right, preventing bubbling or scorching.

4. Let It Cool Completely
Once fused, allow the fabric to cool before handling. This helps the adhesive set properly and avoids lifting at the edges.

5. Trim Seam Allowances
If using interfacing on a garment, cut it slightly smaller than your fabric piece to reduce bulk in the seams. For bags or structured pieces, you can keep the full size for extra stability.
