I just used the fusible strip last night to piece two pieced of batting together and I love it. I ended up with a virtual seamless piece of batting. I ordered mine on-line, can't remember from whom, but I remember it came in varying widths. I bought a roll 1/2 inch wide. You simply place your batting pieced together, lay the tape over the seam and press on a wool setting. Almost instantly I had one large piece of batting. Works wonderfully!
