I've never fused my batts together, but many times have zig-zaged them together or used a very long basting stitch. Our Homemakers club made a quilt for a benefit auction. We used a lot of really small pieces of batting held together with long basting stitches. We tie our quilts, so we thought it needed more ties than most. We put in at least twice as many red yarn ties as normal to hold the batt in place. That quilt brought twice as much money at the auction as our other quilts had been getting.

I also put ALL the little tiniest fuzzy pieces of batting into a box under my sewing table. About once a year, I stuff that into a pillow ticking that I have sewn from some heavier fabric. I give the pillows to the food pantry. People who need food sometimes need a pillow, too. Our food pantry is happy to have them.

I do the same, save those smaller pieces of quilt batting and stitch them lightly together and use them. I usually make a quilt where my 'eyes were bigger than my stomach'.

lol I never throw away batting less than 3 in wide.piece it back together for mug rugs,place mats,table runners etc

I sew mine together all the time...was told years ago to NEVER iron batting because it compresses the fibers, so don't use the iron on tape, but really don't need it. Just butt them up against each other and zig zag away!!

"Heat Press" is the name of the fusible tape. That is the name on the package. I do prefer to use it instead of the zig zag stitch. It is just much easier for me. It doesn't come apart and does not leave a ridge.

the large zig zag is the way to go. I use the iron on seaming tape on the rare occasion when !!! horrors !!! I end up without enough batting at the end of a quilt and it is on my longarm frame. This only happened once but that tape that you iron on saved me since I did not have to remove it from the frame nor hand stitch the battings together standing at the frame.

I put the pieces side by side and zigzag

I overlap them, trim them (with rotary cutter) so they match perfectly, and zig-zag them. Perfectly fine, usable batting!! You can't tell they've been stitched together once they're inside a quilt :)

I slightly overlap and run a walking foot over it with a very large cross stitch or do a whip stitch by hand.

My LA quilter gave me worlds of battng scraps that she didn't want and her customers didn't want. I spent a couple of hours with a ruler and a rotary cutter getting the edges straight (yes, I know some people want the edges curvey) and then I butted the edges and zigzagged them together on my sewing machine. You don't need to press them. No one can tell where the seams are once the project is quilted and you can feel good about how trifty you are. Merry Christmas. froggyintexas
