Rib stitching? Yep. I doped on about a million little bitty pieces of thread spaced at 5/16 inch and then cut about a million pieces of hair paper to make the reinforcing tape. Cover that with pinked tape and you have it. Takes forever plus one week to do. If I were going to do this again, I'd make a jig with small tacks or brads and wind the thread back and forth around them and then would slide the tissue under the thread and dope the thread to the paper. Then I'd cut the paper and thread to the correct width and dope the whole thing to the panels. Doing it that way would save untold hours of labor, plus you would have the stitching at the exact angles that you want. You don't go blind that way either.
