Double Fusible Interfacing
Heavyweight
For a temporary fuse use a hot, dry iron for 5 seconds.
For a permanent fuse, use a hot steam iron for 10 seconds on both sides and leave on board to cool.
Interfacing is a material used to give additional strength, support, or shape to sewing, quilting, and crafts projects. It is not intended to be visible in the finished project but is either sewn or fused to the wrong side of the fabric. It is commonly used in sewing to reinforce buttonholes, stiffen collars and cuffs, and strengthen waistbands. Interfacing can be used in quilting to apply an applique, stabilize a lighter fabric, and prevent fraying.
Happy sewing :)
