I should probably start by saying that typically I sketch my layouts by hand. I've long since been a fan of Becky Fleck and I just keep thinking... I wonder how she does that... Well, I've been playing with a bunch of different software this evening and I'm thinking I need to do some more research but I was so excited I decided to make do with what I have and forge ahead. Here is my sketch!
If you decide to use it please post a link in the comments so I can come and check it out.
