Pick your Interfacing!

December 3, 2010

Many patterns call for interfacing but most also don't expand on which interfacing to use for that pattern. There are many different interfacings to choose from. I'm going to break it down for you to make it easier to pick the right interfacing for your finished project. Interfacings can be divided into weights and fusible/sew-in. Which one to choose depends on your fabric and your project. Some patterns will tell you whether or not to use fusible or sew-in but generally not which weight to use. Interfacing is a fabric that is applied to the wrongside of fabric to add stability, stiffen, strengthen, add body, or to help a fabric keep shape. When making pillows out of quilting cotton, I always add an interfacing to the back to help the fabric hold up and to keep a better shape. I also add interfacing when using Home Décor fabric to make a bag. It helps the fabric keep a structured shape and to also help it hold up to daily wear.

Weight: This is where there is the greatest choice among interfacings. There are 101 different weights (or so it seems). My rule of thumb is choose an interfacing that is directly proportional to your fabric. If you are using a lightweight fabric like quilting cotton, linen, or shirting, choose a light weight interfacing. Home décor projects are a heavier weight fabric and need a heavier weight interfacing. Interfacing Home Décor fabric ensures that window seat cushions last longer and look pretty and pillows keep their shape not matter how many times fluffed. The ultimate heavy weight interfacing is called Peltex. It is used in some of Amy Butler's luggage patterns and can also be used to make fabric storage. Peltex is really stiff and can stand on its own. It is great for adding a lot of body and structure.

Sew-in vs. fusible: Whether you use sew-in or fusible depends on the project and what you want to finished product to look like. Fusible will affect the drape and flow of the fabric. If you are adding pleats, tucks and folds, fusible is appealing since it will add structure to these details. If you are adding gathers or draping, sew-in adds the body and durability but does not affect the drape of the fabric as much as fusible. You can still play with the fabric and add less structured details.

Knits: Knits are such a wild creature that they have their own interfacing category. Knit interfacings are NON-WOVEN and somewhat elastic to mimic knits stretch. This allows the interfacing to add body and strength without distorting knits natural stretch and drape. Knit interfacing are typically around the neckline facings and other places that need some support like buttons holes and zippers.

Psst: The top picture if of Amy Butler's Modern Diaper Bag which used lightweight interfacing and Peltex for the bottom. The bottom picture is Peltex fused on to the back of quilting cotton and made into fabric magnets. Project found here!
