Good for you. I don't think the crossing lines rule holds anymore with all the loopy, geometric, stars and such I see on many quilts quilted on our home machines. This is one of the most fun parts of quilting and I'm not going to let the quilting police see my quilt anyway. One tip, take one of those small post it notes, or sticky dots and write down the settings after your practice and stick it right on the machine. It removes with no residue when the project is finished. I do this with decorative stitches too, especially if I've changed any of the default settings. Have fun.
