We found a large old-school chalkboard at a recycle center and converted it into a family memo board, calendar and catch-all for organizing keys, mail and cell phones.
Clean the chalkboard. Use a tape measure and some math to determine equal spacing for your calendar. We laid ours out with six days running vertically and Sunday sitting across the bottom of the other days. Use chalk to mark your lines.
While the paint is drying on the upper lines, place the baskets (we used three) so they are centered across the board. Use a washer and screws to attach the baskets to the chalkboard. Make sure the screws don't extend past the back of the chalkboard otherwise they may scratch your walls.
