I use the iron on batting tape. Why bother cutting your own when the tape comes on a roll ready to use. The seam doesn't show and no bulk of overlap.

I've used a somewhat large zig-zag stitch to piece abutting batting scraps together for years, and the results have been fine. I have used the basting tape available at many on-line stores, JoAnn's, Nancy's Notions, etc., but the next time I buy any more I will buy larger rolls, but it has worked well also.

I always learn new things on this blog site. Today I have learned from QuiltE about putting batting scraps together with angled lines. Makes sense and I like the idea of keeping thr 'patchwork' bat project close at hand. Lots of great ideas here today.

Thank you, QuilterPurpleDog!

I buy fusible interfacing by the yard using a JoAnns coupon, then cut it into long strips about 2 1/2 in wide, I butt the batting together then use a pressing cloth and steam iron and fuse the pieces together it works better for me than using the tape that is made for that... I put the interfacing on the back of the batting, that would be the smoother side.. pimples up, dimples down, that's how I tell the front from the back on the batting, then the interfacing that you use will be next to the backing and it won't show through, although mine never does anyway.

When someone says the right side of batting. What difference does it make? The right side to the backing or to the quilt top? LOL

You had me laughing out loud!

:DLikewise for me ....... and now, I don't think we will EVER forget which way is up/down!:D

Many thanks to all who offered advice. I am now happily -- and thriftily -- piecing away!

Happy for you, that you have found a way that works for you to turn the trimmings into something more usable!
