Fabric is not always stitched. Most homebuilders are aware that it is sometimes
glued to the structure but most are not familiar with the many other
time-tested methods. On some airframes it is attached with canes & nails (!)
and for metal ribs, with spring clips, wire, sheet metal screws and even
rivets. When Razorback is attached with these methods you end up with a
virtually permanent skin.

John Dyke's prototype, N555A (I hope I got that right), has the fabric
riveted to the elevon ribs, rudder and tailfin. It is glued to the belly.
