Thanks for the tip.....never heard of batting tape. I just zig zag my pieces together for small projects and practice pieces. I save all my batting scraps....hate to through anything out.

I don't know either and I'm in Texas, USA. What I do with pieces of batting is lay them one on top of the other, use my rotary cutter to be sure I've got a good uniform edge and then zigzag them together. There is no evidence of the piecing after you get it quilted. What's more, it's kind of fun to do.

I've never done this for a big quilt, but wall hangings, purses, etc., haven't been any trouble. What's more, I know long armers who do this when they have an extra large quilt to do.

senior center by me collects all the little stuff and uses it to stuff pillows for the hospital pts.

They make the best dust rags, especially for electronics. And tonight I was putting my grandma's china in those quilted storage keepers & I used batting pieces between the plates instead of the silly plastic pieces they included.

I usually just zigzag them togather. Works well

Keepsake Quilting has the same thing, but cheaper

I stitch the smaller pieces together and use them for wall or lap quilts.

You can use light weight fussible interfacing to fuss them together.

When you zig zag the pieces together do you overlap at all or only butt together?

I use the small pieces to dust, and they work great!
