Using flannel for batting...How to quilt
 

Normally when using 80/20 batting for quilts, I quilt on the diagonal 3" a part, both ways, so looks like a diagpnal pattern.
Now I'm using flannel for batting
? is is...can I just sew on one diagonal line? Batting can shilft do I have to worry about the flannel shilfting? I think NO but I need your opinioin.

I sew for Project Linus so don't want any issues.

if spray or pin basted smoothly you won't have any problems. I've used up some old flannel stash for batt in a number of my bed runners. no problems. Unless in your case it hasn't been preshrunk. wash the quilts after quilting to make sure you don't end up with a wadded mess.

OK, I did prewash the flannel so guress I'm ok.

I've used flannel for backing and for batting. Seem to have no problem with it. Sometimes using flannel on the back makes for a little lighter in weight quilt but is still warm. Especially nice for baby or kid's quilt.
