Todays Playing

Today I thought I'd play again with Patsy Thompson's feathers and my own.
I've drawn out two areas about the size of a normal piece of paper. One the left I have just drawn a vague spine, like a question mark like Patsy guides you. On the right I've drawn a normal feather. I have given it a double spine and I've just realized I don't want that for this technique, so I'll just ignore that.
I want to see what these look like side by side.
I found out just now that it's not a good idea to try and draw on an ironing board. Far too soft.
I'll post more pictures as I do each stage.
