Check out Diane Gaudynski's book Guide To Machine Quilting. She has a technique in the book for freemotion crosshatching using a richochet motion. It is a nice technique and I am no free motion expert. It does take some practice but it eliminates all of the the stopping and starting and gives a nice effect. I found a copy at my local library. Yours may have a copy of it as well. It is definitely worth checking out.
