"Innie" is a point on the inside part of the design, like the bottom of a letter "v". "Outie" is a point like the point of the "v" turned upside down. Hope that makes sense! I use a narrow zig-zag stitch with invisible nylon thread on top and thread (not as narrow as the satin, just enough to catch the edge of the applique)that matches the applique color in the bobbin.
