I put one up as I was working on the Hexagon Star as I couldn't keep myself straight part of the time. When you can put the blocks up, stand back and decide placement, etc., it just makes it so much easier. I used insulation board as the base and now I wouldn't be without one. Best investment ever, in my opinion to help newbies along the way. No more leaning over the bed or crawling around on the floor! My body parts didn't like that.
