I just tried the zig zag approach recently after I read a previous thread about it. It has worked wonderfully! I sewed three larger pieces or warm and natural together, and you can't even tell where the seams are! I'm going to work through my batting stash and I think I'll have enough to finish up at least a few more children's blankets before I need to buy more. :)

i too butt the edges together & zigzag them when i need to piece batting scraps- another good use for batting scraps is to cut them into squares & use them for raggy quilt blocks- i always have a stack of 9" & 6" batting scraps- then if i feel like making a raggy quilt i cut fabric (or build blocks) to either 10" or 7" squares , sandwich them, X stitch across the 3 layers, sew them together into rows, then into a quilt top- clip,(shake, shake, shake) wash (shake, shake, shake), dry (shake, shake, shake) -done... :)

I whipstitch pieces together..Real tiny pieces become stuffing for dog beds or stuffed animals I make...I throw nothing away!

I just did an entire lap quilt(50x72) w/ pieced batting - and you can't even tell. I zig-zagged the pieces.

I do the same thing, zig zag them together. It works. Thenks for the tip if there is a wrinkle, iron it.

Some bats are getting very expensive, I can't afford to not use the scraps. I've even put different types together. Never mixed wool bats in but just about everything else. If it looks like it is about the same thickness, together it goes. :)

I love the idea about using fusible interfacing - so inexpensive - I usually save mine - I write on a piece of paper the kind it is and the size and safety pin it to the batting - no more time wasted measuring pieces that I have already measured several times before - I love being able to use up the pieces - I make scrap quilts so it really makes sense to scrap piece my batting too.

I never throw decent pieces of batting away. I butt them up and zig zag them together. Works fine.

I sew mine together all the time. I hate to waste anything. I use a wide long zig zag stitch. If they are wrinkled, I just toss them into the dryer for a couple of minutes to fluff.

you can zig zag the pcs or use for mini quilts, wall hangings or pot holders. have fun.

I save the inch size pcs to put in dog beds. I have four and make a dozen a yr at least for the area pet shelters. concrete floors are COLD!!:(
