I was looking on the Handi Quilter site today & came across this this video with a lady named Helen Godden from Australia. She is not a quilt piecer but she does very unique FM quilting on painted fabric, etc. What I came away with is how she uses guide lines in her quilting to make her designs. I thought some others might benefit from watching her. You will need to scroll down to the video that says "HQ Live with Helen Godden". It's 42 minutes long & well worth the viewing in my opinion.
