I buy the king size battings (120x120) for every large quilt....there is almost always a large piece that can be saved and pieced in on smaller lap quilts and such.....best way I know to save money and still have batting on hand......that and buy from Connecting Threads when it is on sale....35% off now!

I piece my batting all the time ,I agree with Girlfriend sure save a bunch ,I use it in pot holders place mats and any other small projects. Good luck.

I have no qualms about piecing battings to fit and not waste it. Once it's quilted, it's all the same anyway...

All the time. I get to use up my scraps. Just another form of scrappy quilt. If I quilt it well, absolutely no problems at all.

Batting tape is a knit tape with bonding on the back. It is about 2 inches wide. Mine is made by Pellon. You lay it over the joinings of the batting, and just touch the tip of your iron to it to glue it to the batting. If you do this enough it is like basting so doesn't mash the batting. Just quilt right over it andyou can't tell where it was pieced. I used this just recently for the first time, and it is sure faster than hand sewing or even zig zag with the machine.

The quilts I make are usually 96 x 96. I see nothing wrong with piecing the batt together, usually butt it together and join with a zigzag stitch. It never lies flat. What am I doing wrong?

Emma S, try loosening the tension a little when sewing together. Or lay some scraps of old pattern tissue on top where you're going to sew.

I've done it once and will do it again if need be! I try not to waste anything.

I do it all the time. At first I did a quick slip stitch, then I started piecing the batting pieces together, first by straightening the edges (if necessary), then using a large zig-zag stitch stitched the pieces together, which makes a strong piece of batting for quilting. It's especially useful when making small wall hangings, I just use the left over batting pieces so there is little waste, which is important, especially with the price of batting.
