How To Apply Fusible Interfacing - Sewing Tips

Here's a quick how-to for applying fusible interfacing to your fabric. Fusible interfacing is great for when you need to add stability to your fabric, and it will only take you a few minutes to iron it onto the back side of the fabric. No pinning or basting - take a look!

First, just a few words for those who are to do their first project with interfacing:

There are many types of interfacing, varying in thickness, stiffness, and materials used. We're not listing them all here, as another post is on its way to cover that topic. There are basically two ways to apply it, depending on the type: non-fusible (you need to sew it to the back of the fabric) and the one I prefer (and you might too): fusible interfacing. If you're reading this post, you are interested in the latter one.

Now, let's get down to work as you are probably already holding your piece in your hands, eager to go on with your sewing project.

How To Apply Fusible Interfacing


A) Stiff or thick interfacing: CUT ON STITCHING LINE:

First off, you'll need to cut your interfacing pieces using the same pattern pieces as for the main fabric. However, you'll cut the interfacing piece along the stitching line to reduce bulk, meaning you trim off any seam allowance before fusing. Your fabric piece will look like this one when you place interfacing on it:

B) If you're fusing lightweight interfacing, there's no need to trim off the seam allowance. Your piece of interfacing will be the same size as the main fabric. See here:

1. Place your fabric FACE DOWN on an ironing board. You need to apply the fusible interfacing to the backside of your fabric pieces.

2. Place your piece of interfacing on the fabric, the adhesive coating must face down.

3. Cover with a cloth to prevent direct contact of the adhesive with the iron (yes the adhesive sometimes sticks onto the ironing plate if you press directly, as it melts).

4. Apply iron carefully. Press, up, press, up. Don't glide, to avoid shifting any of the layers!

    1. sandi,
      a good question, and you'll find a lot of differing opinions on the net. First off, I recommend following the manufacturer's instructions for the type of interfacing you use. If there are none, going with dry (no steam) pressing is a safe bet. If no effect (the materials don't stick together), try dampening the cloth you are using to iron over.

      Having said this, I use steam sometimes, and only with a certain type of interfacing - but I'd usually advise against that, unless you 'know' your (interfacing) material and when you are certain the steam won't damage it.

  3. I remember the first time I applied fusible interfacing. It all seemed so confusing, but once you know how, it's easy. A great tutorial as always, Damjana. Featured today.

    1. Thanks for the clarification, I learned that a dry iron was best for my pellon 911f interfacing.
