kits sold with pin and lengths of colorful thread.. pins were inserted in a predetermined pattern on black velvet backgroun and strings were wrapped arround to form pictures and psychadelic patterns ... many were meant for black lights
Considered to be pop art, this fad was a challenge. You could choose from a variety of unassembled kits ranging from ships to animals. The kits included a board (often covered in black velvet), nails, and enough string that had to be wound around the nails as instructed. They took many hours to complete and could hung on the wall as a conversation piece.
