The Pacific Arc portable drafting board is a terrific item and perfect for anyone who doesn't have room for a drafting table. It can be used on any table top, even transported to a job site. It has fold-out legs that raise it to the perfect angle for drafting, has a sliding parallel bar that functions perfectly and served me well for many years until the movers broke it. After searching like mad, I was thrilled to find another one at Texas Art Supply. Everyone at the store was very helpful in helping me to locate it, and on sale too! Yay!
