I've channel quilted every 2" the full length of king size tumbling blocks quilt. My question is: should I still cross quilt to be sure batting will stay put in those long 2"-apart-channels?
Warm & White batting says can quilt up to 10" apart. Customer service lady at Warm Co. assured me on the phone today that the 2" channels would be plenty, but I'm still wondering if I should trust that the batting in those channels will be sufficiently stitched down to avoid later laundering rigors.
I'm more inclined to trust the experienced input of my quilting friends on this website!
Thanks in advance for any insights you can offer.
