Monfil presents: Heirloom Premium 80/20 Fusible Cotton Blend Batting: double sided iron-on batting. This batting eliminates the need for the time consuming steps of pinning or basting. Only Hobbs can make this unique product: Fusible Cotton Blend is manufactured in the same manner as our Premium 80/20 in the natural cotton. This batting is made with 80% natural cotton and 20% polyester. It is lightly needle punched and resin bonded to provide exceptional strength and durability. Furthermore, this product has an additional fusible resin applied to both front and back. Heirloom Fusible, if prewashed, will be rendered non-fusible. When washed, the product becomes similar to Heirloom Premium 80/20 Cotton batting.
