Watson ---- I think they look good. We are our own worse critic. ;-)
There are 2 things that helped me:
1. Doodle on a large notepad. Be careful and not make the spirals too small ... which is the tendency when doodling. Target close to the size you think you will be quilting.
2. An on-line video (can't remember who) demonstrated how to move to another spot by "echoing" existing swirls to get to the starting point of the next swirl. It seemed to make them flow easier for me.
Keep it up!
