Rick...actually, I went to a gasket company..(in Kansas!)...and asked what they had..they showed me a catalogue and asked how many yards of the 4 ft. wide stuff I wanted.*grin*..well, I pointed and said maybe a foot....and the guy went to a scrap bin and gave me a small piece...maybe enough for 2 harps...I still have over half of it. It is more resilient..(no grooves after 20 years!)..I just cut strips and glued 'em on the bars and cut notches. I assume that gasket companies still have these sample books with 101 different styles and thickness and resiliencys of felt, but I have not looked in a long time..(I also have a working model of a Zimmerman Harp (with the shifters)from 188X...talk about inventions!!)
