Nothing but a stitch groove and 3/32 punch. Once pattern is cut, I lay out my stitch pattern and punch the holes before airbrush and antique. This keeps the holes from showing like they would if they were punched after dye. When using white thread I like the stitch grooves to to be antiqued before sewing. The antique in the grooves really makes the stitching shine. Stitching is the most important part of a build to me. Nobodies paying hard cash for something with shoddy looking stitches.
