When I did my Colt I left a 1 1/2" flap of the skirt at the deepest part on both sides, in the bottom edge of each flap I punched three 1/8" holes on a row, then I laced these holes from one flap to the other under the saddle with a leather shoelace, puling the middle together... can you picture it? As I said in my first post, the bike crashed and the sadddle was destroyed on its maiden voyage so I don't know how durable my solution would have been. Perhaps chrome eyelets in the holes would be a good thing, available at any good hobby/craft store.
