Thanks guys! I decided to experiment on the wing I already had done thinking I'd have to rip all the covering off and start over anyway. With a little heat I was able to separate the seam where the top covering folded over on to the bottom and then I cut the slits as you said, pulled each tab tight to the scalloped edge and re-ironed them down to the bottom of the wing. Worked great!

Sorry to see your Fokker in such a sorry state khodges, at least it went out in a blaze of glory and not hangar-rashed to death!

Thanks again!
