Embellish™ Fusible Underlay Bold is for use to strengthen and fortify fabrics before embroidering. Prepping the fabric will add the needed fiber count to make even the densest embroidery stitch with perfection without puckering, shredding or damage by constant needle penetration. Embellish™ Fusible Underlay Bold creates a protective barrier without changing the drape or feel of the fabric. Use to add substance to burlap, sweater knit or cotton fabric when creating purses or home décor projects. Can also be used to cover scratch stitches on the inside of a garment.
