sewing batting scraps together
 

I have several large-ish pieces of Warm & Natural cotton batting left from other quilts and need a batting for a small-ish baby quilt. LOL Is there a right or wrong way to zigzag the pieces together like there would be for fabric. There isn't a straight of grain to batting is there?

There isn't a straight of grain in batting as far as I know (which might not be too far). I would try stretching a piece to see if it stretches one way more than the other. Maybe also try tearing a small piece in both directions and see if it tears more easily one way or the other. The stuff I use doesn't stretch in either dimension, and I just use it however I fit it together.

I have only done this with "quilt as you go" methods. I didn't have any trouble, and I didn't worry about grain. Just my opionion though ;)

I make a straight cut on the edge of each side of the pieces I want to sew together. Then i use the 3 stitch zig zag stitch. It stitches perfectly flat and avoids the 'ridge' that a regular zig zag and make. I piece batting together all the time. It is too expensive to waste.

I like the advise you have already received and will add that when I cut the straight edge I usually slightly overlap the two pieces then use a ruler to cut both pieces within the overlapped area. This way the two sides match perfectly even if my cut is not perfectly square.

I love the iron on tape for this. It's about an inch wide. As long as it's the same type batting, joining pieces is fine.

There's no grain with W&N, but there is an "up" side and a "down" side. Just match those when you sew the pieces together and you will be fine. I started out doing the recommended way - cutting a wavy line through both pieces and sewing together by hand - then used the tape for a while - but I've finally decided that zigzagging them together with the sewing machine is just as good, and much faster.

Three stitch zig zag is my method. Works for me.

Oh woe is me, I have to be the one to ask, what is three stitch zig zag?
