808 Reactivating Adhesive is for patterns, papers, and most battings. Shake well and spray lightly - both of these are important - and spray on paper, fabric, or batting. Make your own temporary fusible projects: any regular paper takes on freezer paper properties, most battings become fusible. Does not gum up needles or scissors. Amazing, right?
I especially like to use it on a pattern that needs to be transferred to fabric for tracing. Spray the right wide of the pattern, press it to the wrong side of the fabric, use a light box to trace the lines onto the right side of the fabric. The paper stabilizes the fabric while you trace!
