I got myself an Idea booklet to jot down my ideas and observations. Always good to put down on paper what you have in mind rather than store in memory. There is so much to think about each day; so better to have it in black and white.
I had one when I did Rosenberg Meet a few years back but never got to execute that layout. But it made good sense to check what I had written and see if I could use them for germaN160 layout. Hope you keep one too.
