I like to use a batting when making table runners. Walmart has one that is perfect and quite reasonable. LOOK FOR IT WHERE THEY DISPLAY THEIR FUSIBLES,ETC. For heat resistant, use thermolam, which can be found in the same place. I used to work at Walmarts fabric dept. before they closed are department. The batting I am referring can also be used for wallhangings and was very popular with our customers. Hope this helps.
