I've settled on thin silk. About $12/yard. If you are artistic you can use water colors to add a fashon statement. If not, buy pre-dyed.I build two curved aluminum rods, left/right, sew a loop on the end of the slik that slides onto the rods, and tenson the silk by pushing the ends of the Al rod into holes on the front baffle. Looks a little like the Revels.
