I use Thermore as well.

I soak the batting for at least an hour ( to really saturate all the fibers) then spin , then put in the dryer on cotton. Warm and Natural or Warm and white holds up remarkably well prior to quilt construction . It is one of the reasons I like to use it.
If I am in a hurry I have put it in to soak for 15 minutes and then run the gentle cycle for about 1-2 minutes just to help the saturation. I used to soak in the sink or tub and noticed that after 15 minutes not all the fibers had taken on water ( there were still area lighter in color indicating they had not soaked up water).

I use warm and natural in mine. That seems to work best.

I wash warm and natural on gentle and dry in dryer on lower heat with no problem. I also use in placemats and runners with no problem.

I use a low-loft batting. It decreases the "tippiness" factor of items you may put on the runner. Also I like to roll my runners for storage and the low loft batting makes a nice compact roll.

For table runners and placemats I use either prewashed flannel or thick muslin. It makes them light and I don't get tippy glasses. I know. I'm an odd duck.

Just finished my second table runner for the new island in my kitchen. Used left over fusible fleece. Don't want a lot of loft. Too tippy. Quilting still showed as much as I wanted it to. When the fleese is gone I have some mystery fab I will use for batting. Think it may be sweatshirt material.

So much fun to make. Did use a pattern. Just determined the size and away I went. One has two rows of large flying geese with no center. Just two rows of geese.

The other has a center bordered by half squ triangles.

Now have to make one for Christmas. Whoopee! Get to shop my stash!!

me too. gotten very expensive though and Joann's doesn't carry, so may switch to flannel.
