Hmmm. That sounds like what I've tried, but mine don't look like that! How does the single stroke acheive the nice, gentle arc of the smile? Does it just naturally make that shape, or does it matter how/where you insert the needle from the back? When I have done it, the "smile" is just a straight line. If I pull more taughtly, I get some better cheek definition, but still no arc to the smile. I'll try again.
