For grown-ups
The cards are free. There is no sign-up. Each one prints on one sheet of plain paper.
The colors on a card are only a guide. Any color of brick works. If a piece is missing, try a different one. That is part of the fun.
The bricks in the kits come from families who gave the ones their kids outgrew. See the brick drive.
