Sold Per Yard. French Fuse is 100% polyester with one soft side and one “glue” side. This product allows you “change” the look or texture of your fabric! You can use it to completely underline the back of a knit fabric such as sweater knit or knit pants (gives it a more “tailored” look) or to give soft shaping to collars, facings and hems. French Fuse is a lightweight interfacing with one fusible (glue) side and one soft side. When using French Fuse, cut out your garment FIRST. Lay wrong side up on your ironing board. Place glue side of product to the wrong side of garment and “stick it” by touching dry (medium setting) iron in a few places. This will hold the fusible to the garment piece while you cut away excess. Take it back to the ironing board, take your time and fuse completely with steam. When using French Fuse, you will get a bonded look. Machine wash garment in warm water after fusing, tumble dry with low heat or hang to dry.
