I made hanging earrings holders one year for Christmas presents when I was in college... what I used for the center part was screening mesh from the hardware store. I just cut it a little larger than the opening and glued it on the edges. (I used embroidery hoops for the frames, and then used a ruffled trim around the edge for decoration.) The earrings go through the holes in the screening, so there's not much "wearing out" to it.
Hope that helps!
