Thanks for this! I was just wondering how many runners' worth of batting I could get from the craft/baby size.

Pellon fleece interfacing is the only thing I use for table runners and placemats. It does everything I want it to - flat, but has enough loft for quilting to show, - clingy, so it hardly needs pins. It comes both fusible and non, but I like the non. Candles sit flat.

Me too! Or warm and white, lays flat!

This is what I use also except last Christmas in a rush to finish a gift for DD I was out and used a scrap of batting I had on hand. She loved it but after she had it in her table for a couple of weeks she called me and said it was not working. I ask her if it was too thick. She said, too soft my cats think you made it just for them. Every time I turn my back they push everything I have setting on it off and they are on it sound asleep. So too soft is not good if the user has fur baby's.

I use Warm & Natural, never had any problems with it laying flat on the table.

I use Warm and Natural for absolutely everything, but that's just me.

I like Quilter's Dream Cotton ... the thinnest ... select, I believe.

Last week I ran into a polyester batting at Hobby Lobby that has very low loft which would be good if you were to set candles or other center pieces on the runner. It was 45" wide. I bought it to add to a quilt that I was backing with Minky and didn't want too much added weight. Might take a look.
