J D, I used some of Glenns fabric for the cockpit area. Its a course linen and I didn't want to try it on the wings. Also with the wire trailing edge you would have to sew the top and bottom together and I don't know how that would work. Get a 15'x45" roll of Super Coverite to do the top wing. They don't make it anymore but I have seen several on Ebay lately. You have to cover the top wing in one piece to get it to look right. Also Glenn's D-8 cockpit stuff will all work in the D-7 with minor modification. Have fun building, its a lot of work but a really impresive airplane when finished. I should be done next week and I'll get some more pictures then. Don
