Janet's Influence - quilted ferns

I've started quilting, working from the bottom up, in an intuitive manner. The fabrics are telling me to go with a nature theme, and I've been thinking about ferns, so that is what I quilted. The only marking was a lightly chalked central vein. The charm about the powdered chalks is that you can quickly rubb out the design with your hand if you don't like what you've drawn, and by the time the quilting is finished, it's gone. The problem is that you can't mark too much at a time.
