Inspired by a folding paper cup I used to make as a child that tapered towards the base and revealed triangular shapes on the inside from the folding process. I kept a box perimeter and used trapezoids and triangles to taper, creating a multi-faceted form similar to that seen on the F-117 stealth aircraft. Hence, the name “The Hopeless Diamond Sofa” (an early nickname given to the stealth). The focus of this prototype version was to use off the shelf materials found at the local hardware store like copper plumbing pipe, shipping blankets, zip ties, and carpet padding. There are no difficult miters or glued joints!
