I would try some samples with a couple of batting choices to get the look you want. The flannel will be very flat and your quilt stitches won't sink in like they would on a thicker batting. I use Quilter's Dream poly on a lot of wall hangings. It's also fairly flat but gives a little more definition to your quilting and it's also very stable so your wall hangings don't sag over time.

good job!! i've used flannel as well

I have used flannel , and also for a wall hanging .. i 've used felt the poly type, has nice structure to it for a wall hanging.

I use flannel as batting on all the baby quilts I've made. It has a nicer "hand" to it than regular batting, very supple.

Love your bear!!!

ditto...my grandmother used old flannel sheets for many of her quilts she made in the 30s & 40s

I meant to tell you what a lovely quilt you made :)

It an awesome wall hanging. I love it. Flannel would be find for batting.

Beautiful work !! :-)

Thanks! I've got it going, and it seems to be fine.
