Bring these materials to have the best workshop experience and drawings you can keep and look back at during your journey and for the next time you plan a new chapter.
Velum which is translucent paper that's fun to put over your original mind map drawings so you can preserve the original thoughts and keep looking back at your progress.
This is if you're keeping paper copies, which I always do because I love them, and you want to be able to go back and look at what you discovered along the way. It's really fun to look at your maps and what you dreamt up particularly after you're some way along your roadmap and seeing results.
While you're shopping online or in person for your supplies don't forget to get a binder to keep all your maps tidy and wrinkle free. If you leave them in a pile on the desk you'll be sorry you didn't care better care of them later!
If you're going to do all four workshops, Alfa, Bravo, Charlie and Delta, you'll definitely want to keep the maps all separated so they're easier to refer back to as you get new ideas or you forgot to write something down.
Just like in school when the teachers told you to sign and date your artwork, please do that with every page in your journey! You'll be glad you did when you look back on your plans, like artwork.
