Variations and Extensions
The bead stair consists of 9 segments of wire strung with one to nine beads. Every number of beads is done in a different color: 1-red, 2-green, 3-peach, 4-yellow, 5-light blue, 6-lavender, 7-white, 8-brown, 9-dark blue. The beads should be as spherical as possible so that they are equally wide as long. They should measure between 7 and 8mm in diameter.
