But sticky notes are not the only tool I use. For the layout on the fabric (and determining, therefore, how much fabric to order), I used LibreOffice's draw tool, with a scale of 1" = 1':
Now all I need to get going is weather decent enough to go out and lay out the cuts on the fabric... out on the dock. Can't do it inside - the panels are 12 feet long.
Waiting for spring...
