I use the tater bag batting as it is thinner for runners and I iron on light weight fusable facing on the back. I don't use any batting or facing on table cloths as I just hem around the table cloth.

Flannel will work nicely :D prewash and dry twice to preshrink it :D:D:D

Does everyone quilt their tablecloths even when they have no batting? When you have a backing do you make the tablecloth reversible?

if you made pieced blocks for the front of the tablecloth, yes i would do some quilting just to make sure they stay together over years of use and washings.
if you use flannel, wash it and dry to shrink it well.

Yes, I quilt, even without batting.

I would certainly pre-shrink any flannel...its just too unpredictable!! But I do like the idea of only the top and a flannel backing without batting. Sometimes the batting is way too think for a table topper, especially if there are lots of seams in the pattern.

Yes, I do too.

Pre-washed/pre-shrunk flannel
