I just use warm & natural.

I've used fusible interfacing. I've also used non fusible, but spray basted it. I bought some poly felt as someone on the board suggested, but have not tried it yet. I've tried about everything available for the inners of tablerunners.

Maybe I'm the only one, but I don't put anything between the top and backing of both tableclothes and tablerunners.

White felt. Washes fine.

Same use that for most everything

i use flusible fleece for runners and wallhanging love it

W & N works great for my runners and placemats.
