For the quilt-along I am following, I started a bit late, they are already on Week Three.
To catch up, I did Week One and Week Two of the Free-Motion Project’s quilt-along yesterday. I’ve been FMQing a few years now and have never managed stippling. The random movement eluded me for some reason. But by the time I was done yesterday, I was having fun, and now I’m trying to decide which of my many UFOs to stipple. I think I’ll end up doing some stippling, but not the entire quilt, on two different projects.
Here’s Week One’s result – 
You can see where I started with simple U shapes to the left, and I shifted to smaller ones after 3 rows. The smaller ones were easier for me. On the right is my attempt to do Y shapes and lobster claws in rows. There are a few in there –
but I kept getting carried away by the wiggling motion. Wheee! My lobster claws grew barnacles.
For Week Two, I started with simple Us down the center to divide my practice sandwich. 
Can you tell which side is the random, start-in-the-center version and which is the rows? I couldn’t either. I labeled these two pieces so I could remember later which week was which, and included a notation for random and rows. As I took pictures, I looked closer, and found where I had done my center start – 
– and I had my label wrong!
Here’s the random version – 
And the row version – 
Don’t believe me? Start at the lower left in the last pic and follow the stitching with your finger. See? Three rows. Kinda lumpy ones, which lets them blend together, but it worked for me.
