I save most of my batting scraps.I use the small ones for purse and other small projects. I zigzag the bigger ones together for use in another quilt. Works pretty well for me, except i sometimes find the edges stretch if I'm not careful. I was at the quilt store the other day and saw batting seam tape and thought I would try it. It is great, i had the batting pieces together in no time. Fuses very well with a steam iron, I was very happy with it. the brand i used was Bosal Batting Seam Tape, ( 1 1/2" by 10 yds). Cost about $5.
