Yes, my friend (who shall remain nameless but you know who you are) these really and truly are unmarked free-hand fans in Little Pink Houses.
Quilting arcs a half-inch apart helps to make them smoother. Still, by the time I got to the top of this little (23" x 21") quilt, there was a good 1 1/2" difference between the top of the highest fan unit in this row and the lowest fan unit. Here's a pic where I have those two points marked. See, one way high, one way low. And it doesn't matter.
I know I'm a broken record on this point, but you just have to relax and enjoy the process of doing these free-hand fans. They WILL look great when you are done. And the more you do these, the better they will look. Practise, practise, practise.
On a completely different note: Tazzie, I enjoyed your comment. I'd love to see your blog but right now it's blocked. If that's on purpose and you're not ready to share, no worries. On the other hand if you're wondering why no one visits your blog, there's an answer.
