Interfacing Secrets


Louise Cutting, a Threads contributing editor, shares her professional knowledge about interfacing products. Much of her information comes from snoop-shopping in high-end ready-to-wear garments. Discover clever techniques for using fusible interfacing in a range of garment areas.

Interfacing plus underlining

Often, a jacket front is fully interfaced with a fusible product. This creates a crisp effect. Instead, learn from designer Giorgio Armani, and apply the interfacing to a cotton batiste underlining. The results are soft and sweaterlike.

Cuff and collar treatment

Standard garment pattern instructions say to interface a cuff’s facing, or the undercollar. Louise advocates fusing interfacing to the cuff or collar itself, on the “public side” of the element. You’ll have a smoother finish, and the seam allowances won’t show through.

Patch pockets

If you’re interfacing the upper and undercollar, be sure to use a lighter weight interfacing.

 Hems on knits

Serge a strip of fusible interfacing, cut on the crossgrain, to the hem edge of a knit velvet. Make sure the nonfusible side is against the fabric’s wrong side. Fold the hem up and steam to fuse. The interfacing secures the hem in place. Apply a loose, hand-worked catchstitch to permanently secure the hem.

Stretch wovens

When you’re interfacing a fabric that has some stretch, cut a knit interfacing with the pattern’s grainline on the interfacing’s crossgrain. This maintains stretch in the interfacing piece, so it can move with the fabric.
