This is #3 for Quilting. This is called wavy lines. It is my first true attempt at using a darning foot, doing actual FMQing. I did draw the wavy lines, but as this was the real first try at controlling not only the foot pedal, but trying to keep a steady movement of the fabric, it isn't a pretty curve. They are somewhat jagged as I wandered off of my lines. And I didn't space the curved lines properly.
Overall, I guess it's fair for a first true FMQing try
I used a reddish thread, front and back because the majority of the colour is in the reddish range on either side. It shows well enough for you who wish to critique my attempt.
