I like to do loops with leaves or stars or hearts. As long as the amount of quilting is consistent, any design will look fine. I also do a lot of meandering. The way I keep the size of my turns about the same size is to imagine going around a coin. If I want it to to be big curvy lines, I think about going around a 50 cent piece, first in one direction and then the other. If I want it tighter, I imagine going around a nickel or dime. Good luck!
