When sewing on terry or any fabric with loops and nap, generally a topping stabilizer is used. These can be helpful, but have a limitation: They do not hold down the nap past the actual stitch, which means outlines can be lost in the surrounding fabric. Using Knockdown you can create a global underlay for the entire design. The underlay extends a few millimeters past the edge of the design, which helps the overall effect.
This product revolutionizes the sewing process as applied to towels – no more need for expensive topping stabilizers (Solvy for example) – the stitching automatically flattens the surface, allowing the design stitches to show beautifully, without nesting in the pile of the towel.
