May demonstrates how to use iron-on interfacing (such as the Stayflex Iron-on Interlining). When you iron on the interfacing it will stiffen the top layer fabric. However, the stiffening should not overpower the garment it is supporting.
May advises to always test the interfacing fabric to see how much it stiffens. If you are unsure, always purchase a lighter weight interfacing, as you can always use two layers of a light weight interface fabric.
May strongly advises that you take care when using interfacing fabrics, as the glue can spread into unwanted areas. She also explains how iron-on interfacing may distort the outer fabric. She tells us to first cut out the pattern piece you want to interface and lay it on the interface fabric. Be sure to press the iron on top of the fabric (do not push the iron side to side). The beads of glue will stick the fabric in place.
May recommends using an oven liner when using any kind of adhesive on fabric. Place the oven liver over your ironing board. Any sticky substance will transfer to the liner rather than you ironing board, so no glue will be transferred to your next piece of fabric.
May compares the different interfacing options available from Fabric Land. She explains the benefits of each one:
- StayFlex is a heavy iron-on cotton. It is great for when you need very stiff fabric, such as a stand-up collar.
- Iron-on Vilene is well-suited to fine fabric garments, such as summer dresses and shirts.
- Knitted interfacing material is well-suited for both knitted and woven fabrics. It has good mobility and is very soft.
- Tailors canvas need to be hand stitched in. It has a good weight to use on most woollen garments. Its movement stops the fabric from being too stiff.
- Interfacing paper is perfect for applying shapes onto a background. May givers her top tips on how to use this interfacing technique correctly.
- All the examples of interfacing fabrics are available in both black and white.
