I love that accordian file box idea. Got to get one of those.
At the moment I have a file with the clear plastic folders that you can insert. Its working okay I have to say, but would like to file my blocks in alphabetical when we get going.
I usually print out a colour copy of the block with the template and then go from there. It worked till I got to BR2 LOL I am going to have to make that over it was unpicked so many times it looks awful.
