How to Use Fusible Interfacing

Fusible interfacing is one of the most useful types of interfacing there are. When done right, it makes the difference between something that looks professional and amateur.

It has a plastic coated side that makes it stick to fabric when pressed, that's why it's also called iron-on interfacing. Once applied, it gives stiffness and strength to any fabric

It's used to make buttonholes, zipper edges, pockets and seams resistant to constant use. You will find it in handbags and shirt collars too. It gives them body and helps them maintain their shape.

This type of interfacing is very useful and easier to work with than sew-in, but it takes practice to get the perfect bond. Here are some tips to help you get it right.

Ironing Fusible Interfacing

Fusible interfacing doesn't work so great on thick fabrics or ones that don't resist heat. It will also change the fabric's original drape if their weights don't match.

Before applying, make a small sample to ensure that you get exactly what you want. If it doesn't come out the way you hoped, select another type and test again.

Here are the steps to selecting the right interfacing everytime.

When you get exactly what you need need, you're ready to fuse!

How to use fusible interfacing

Tip

Fusible interfacing can make your fabric very bulky, especially if you have to sew many layers together. Leave the seam allowances without interfacing to reduce bulk and make sewing easier.
  1. Pin the wrong side of the fabric to the fusible side of the interfacing. (This is the side that either looks shiny or has glue beads. Hold it up against the light to see the difference).
  2. Cut the interfacing around the fabric and remove the pins.
  3. Cover the ironing board with a cloth or large piece of paper. This will protect it and avoid you getting it all sticky!
  4. Put the fabric on the board with it's right side downwards. Place the piece of interfacing on top, fusible side towards the bottom.
  5. Cover it with a second cloth. This will protect the fabric from the high heat settings and the iron from sticking to the interfacing.
  6. Press the iron down and release some steam. (If the iron doesn't have steam setting, dampen the cloth before pressing) Leave it for a few seconds, and bring it up again.

    Note: Most types of interfacing will fuse better with steam. BUT there are some that will shrink. Make sure you test with a scrap to see if you can use steam or not.

  7. Move the iron, and repeat this process until you have pressed the whole piece. Don't move your fabric until it cools down.
  8. When the fabric is cool, turn it over and iron the front, wait until it's cool again before moving it.
  9. Make sure the interfacing is completely fused to the fabric. If you notice air bubbles or lose parts, repeat the process.
  10. Once you're sure the fabric is perfectly bonded, finish the piece's edge with a serger or zig zag stitch.

Yay, you're done!
