How to Fix Bubbles in Fusible Interfacing and Prevent Them in the First Place

Don’t you hate when you wash something you have sewn and when it comes out of the dryer there are bubbles in the interfacing? It’s annoying because it makes the garment not lay properly, and sometimes it can even make the garment uncomfortable to wear.

How to Fix Bubbles When They Form in Fusible Interfacing

Don’t despair if you get bubbles in your interfacing. There are a few different things you can try to fix the problem:

  • Use an Iron: Sometimes all you need to do is press the interfacing again and it will lay flat. Of course, this process might have to be repeated every time you wash the item.
  • Pull the Layers Away from Each Other: After the fusible interfacing is all stitched in, sometimes pulling the layers apart can make them lay flat. This is a good solution when the interfacing was only added to the item for thickness, not when it was used to add form.
  • Sew Topstitching Over the Interfacing: Either sew topstitching along the edges or create a quilted pattern. This is actually a pretty good solution because it creates a decorative pattern on the sewn garment. Consider what the finished garment will look like before sewing topstitching or quilting.

How to Prevent Bubbled Interfacing in the First Place

Sometimes bubbles in interfacing are inevitable, but sometimes they can be prevented with a little upfront planning. Use the following tips to prevent interfacing bubbles in the first place:

  • Press the fusible interfacing with an up and down motion instead of back and forth to prevent uneven stretching.
  • Preshrink both the interfacing and the fabric before sewing, unless it is the fusible kind.
  • Make sure the iron has completely heated to the proper temperature before ironing so the glue on the interfacing gets properly heated.
  • Use a press cloth to more evenly distribute heat to the iron-on interfacing. (This protects your iron from the glue better anyway.)
  • Let the newly interfaced fabric cool down completely before handling to prevent uneven stretch.
