Bosal Batting Seam Tape
 
Fusible seam tape for joining scrap pieces of batting.
Like most quilters, you probably have a lot of leftover batting scraps - which again, like most quilters, don't get tossed out. Am I right?! Use this batting seam tape so no batting goes to waste! Layer the two pieces of batting over each other, cut, remove excess, butt the edges of the batting together, lay the batting seam on top where they join, and press. Voila! You've now got a nice piece of batting you can use. Its so soft you can't even tell its there.
