Heirloom Fusible 80/20 Batting Strips - 2.25 in x 25 yds. Roll. Using Fusible Heirloom 80/20 Batting Strips makes creating quilted and sewn bags, purses, straps, rugs, rope bowls , quilt sashing, and a whole host of other sewn and quilted projects a quick and enjoyable process. Since these strips are fusible on both sides, and you'll likely be fusing one side of the batting strip to your fabric strip, place a non-stick mat or parchment paper on your ironing surface to keep the strips from sticking to it when you're pressing the fabric strips to the batting strips.
