Well I have three important pieces I use to support my projects. I work mostly with sketcup, so I have plans and printed cutsheets or suggestions as I call them. Some are just full blown plans. I have a big white board that I use as a giant story stick with dry-ease markers to draw up quick current needs with referenced measurments, or thats where I can deal with oops and any required design changes. I keep a printed copy of plans attached to the white board with a black binder clip and string so I can quickly pick it up for reference and then just drop it and its out of the way but not lost. Finally I have my laptop in the shop with me for any other needs. to be honest my whiteboard is my go to tool and any story sticks i might make.
