I found a stitch that works!! I have two stitches with the single line, then triple line--but they weren't quite wide enough to show (so pretty and delicate though!), so I'm doing to use one that's even thicker. (D-50 on my machine) It should be about the same width as three strands of embroidery thread--which is what it called for.
Now to baste a practice grin.
(I took the afternoon off from work to catch up on fun stuff since I've put in at least 6 hours on school stuff at home lately! :| ;) )
