I don't save a lot of leftover things, really all I save is my quilting leftovers. Stored clutter gives me stress. I will give it away instead of tossing it and that's as green as I'll be.

I have lots of pieces of batting from previous quilts, but I have never used them yet. I have the batting tape, but have never used it yet, either. I think I'm chicken. I always use a full piece of batting.

You gotta do what you gotta do. I've done it often but not on a real arge quilt. My question to you LAQers. Probably not a good idea unless its your own quilt on your own machine? Just thinking there might be more stretching and torque needed on a LAQ frame, or doesn't it matter?

I have not done it yet I save large pieces and think it is a wonderful idea.

You are right to add the extra rather than "size up" for just a few inches. I have a drawer of batting scraps, I use just about every square inch of batting. Its amazing how quickly you can have enough for a project.

How do you sew the batting together so it is a consistent thickness all over? It seems like it would be thicker at the joined edge. I've had issues with it being thicker and thinner just from trying to get it smooth when I'm doing the sandwiching. What am I doing wrong?

I butt the edges and do a whip stitch. This piece was at the edge so it didn't need to be as strong as it would if was closer to the center and taking more strain in construction.

I butt the edges together and use a medium zigzag stitch. It works fine with no added bulk. I have never noticed any stretching or wonkiness but then I don't use a long arm to quilt my messes.

I but them up and zigzag...never had a problem. I do it with all of my quilts.

For smaller items, I have pieced larger pieces leftover from quilting projects. At first, I used to zigzag them together. Then I used the joining stitches. Now I use either flatlocking on the serger or the batting tape. I really like the way the last two methods work.
