This blackboard display with sleep chart is very easy to create with a sewing machine, some scrap fabric, shelf paper, the Cricut cutting machine and a printer.
I cut all the letters out of shelf paper with the Cricut using the Don Juan cartridge. I cut and sewed clouds out of felt, cotton broad cloth, shelf paper, and cork and printed out animals with the regular printer on color paper then put it all together on the Family Commons black board. The line graph is a chart of how much sleep children need as they grow. It drops to 8-9 at 12 years old but before that it is significantly higher.
