And why use it
Interfacing is a great tool to use when sewing. It is can enhance your project, especially clothing and make your sewing really pop. Interface can be confusing though. There are lots of different types and uses which can leave you standing in front of your options utterly confused. In this post I’ll explain to you the uses for interfacing and type you will need for each use.
Two basic types
There are two basic types of interfacing. Fusible and sew in. Fusible has one or both sides of the fabric coated in a heat activated glue so you can iron the interfacing directly to your fabric. It won’t shift around your fabric and is my favorite type. Its drawbacks are that it doesn’t work well with fabric that can’t be ironed. You might choose not to use it if the piece you are attaching it to is the outside of a clothing piece since it can leave a glue outline on the fabric. Sew in interfacing doesn’t have any fusible pieces and has to be sewn onto the fabric. This can be more time consuming and result in more difficulty getting the interface and fabric to line up, but may have a higher quality look and it can be used on fabric that can’t be ironed.
Why use interface?
Helps stiffen fabric to give it shape
When you are working on a structured garment, you may want to use a stiff interfacing that will help the garment hold its shape. Common uses are for defined shoulders or a structured bodice. You’ll want to use a thicker interface, and fusible would be ideal.
Helps fabric lay flat and keeps wrinkles out
Using fusible interfacing can help your fabric lay flat. It isn’t prone to wrinkles so it keeps your fabric wrinkle free. Some people use interface when quilting to help the quilt top lay flat. Again, fusible interfacing would be most useable.
Give fabric strength
Interface is a great way to add another layer to your fabric to give it more strength in high stress areas like the armhole of clothing or the straps of a bag. You can use either type of interfacing when doing this. Make sure it’s a thicker, stronger interfacing.
Fuses fabric together
Double sided fusible interfacing can fuse fabric together without sewing. This is particularly helpful for new sewists and for craft projects. (My wristlet lanyard uses this type of interface)
