Heirloom Fusible by the Roll (96" x 30 yds.) NEW! Hobbs Heirloom Fusible Batting. Hobbs has taken their best selling batt, Heirloom cotton (80% cotton/ 20% polyester)and added the incredible convenience of making it fusible. Hobbs is using a state of the art method of applying a light fusible to the surface of the batt. This fusible is light enough to re-position and re-fuse, should you need to; but it is also heavy enough to allow you to fuse your layers, thereby eliminating the time consuming methods of hand basting. The fusible washes out. Due to the large size of this item an additional $30 surcharge is added to the US shipping.
