I use them for table runners,place mats,purses,and mug rug.I will piece batting for a quilt when needed.

Yup. That's exactly how I do it too.

Also ... I save all of my batting "scraps". Before I quilt anything I make at least one practice sandwich with the same batting, thread and fabric to test my quilting motif, thread combination, tension - everything.

My Viking has a serpentine stitch that I like to use. I haven't tried it on anything large, but for small projects it does a wonderful job.

This is exactly what I do! I have a bolt of this leftover from garment sewing. I just cut me a strip and iron it on. It is either a lightweight or a feather weight, I'm not sure. It is so incredibly cheap at Joanns, much cheaper than the batting tape. 1 yard of this is considerably cheaper than 1 roll of the batting tape and it does the same thing

I sew together as much as I can, like you said this stuff is not inexpensive. I don't use the standard zig zag, but the one that is multiple little baby stitches, with this stitch mine just lay down a little flatter

JoAnn's sells fusible TRICOT interfacing by the yard - it's whisper thin, undetectable and softsoftsoft - it's the same material used to make those expensive rolls of batting tape. Buy the yardage, cut it into 1-1/2" wide strips and fuse away. It's so much cheaper with very little work.

Thanks for this tip. What a great idea.

Ghostrider, that is the way they put wallpaper up, only they cut a straight line instead of curvy. Good goin'.

i've been piecing batting by butting the pieces & zigzagging them for years- have never had a problem with it & really can't see any reason to spend money of some special tape-that probably takes just as long as my zigzagging-

Feather stitch works well but I like using fuseable interfacing cut in strips.
