So I tried it and had to post it right away, because it was so much fun! I just threw a double needle in my machine, threaded her all up, and sewed along my mock style line. I decided to start with denim because it was less intimidating than chiffon, but will be trying that next. Once your line is sewn, simply pull the bobbin thread taut, bringing the two stitch lines together and forcing the pin tuck upwards. It took a little manipulation, and must say it feels a little delicate. However, this is my first try and I'm sure it takes a little customizing with the stitch length and such. Very exciting though. I definitely achieved the look I was going for! Click on the pictures to see ultra close-ups.
