I'd like to see what Jerry decides to do and how it works after all the suggestions. I too have an Avocet Touring W-1 saddle on a bike my ex left behind where the covering is a bit wrinkled on one flap that I want to get around to fixing one day. I have a slightly older Touring 1 saddle on another bike which is fine, but the women's bike spent a long time hanging in the garage. Also, these saddles have very concave sides due to the wide rear part, so require more tension in the covering in the flap areas. Anyway, I was thinking of peeling back the covering from the flap in the wrinkled area and using some 3M Super 77 spray adhesive. The thing is, there is a layer of foam between the leather and the plastic base, so you don't want the adhesive dissolving the foam.
