there are lots of thin batts on the market- any thin batting will work- or flannel- or even just a layer of muslin-

How about a piece of thicker muslin? I have used it for placemats and it is fabulous.

i always use 80/20 cotton,that is just my personal preference, I love the puckered look
It still drapes nicely and it looks very nice.

Flannel

Pellon makes an interfacing with low loft for placemats and table runners. It is 45" wide and available in both fusible and sew-in. I sold it at JoAnn's in the 90s and recently bought some more there.

See if you can locate an old sheet blanket. They give a little loft but are very drapable.

I've used flannel several times and found that it works great.

Thanks everyone! Looks I have lots of options :thumbup:
