Here's a very simple method I used to put stitching on my Duncon Hudson 1/4 Tigermoth.... It really look good and did not take a lot of effort! I used 1/8 in to 1/4 in pinking tape depending on where on the plane I was working. On top of the tape I applied Elmer's wood glue using a T pin. dabbing the T pin a 1/4 in or so, or what scale required. This was done over silk covering and when painted it looks great!
