By using some items from your home, you can introduce children to recycling and reusing. Your art center does not have to be fancy. A table and chairs will do fine. If you have space for an easel, it is a wonderful way for children to work too. A floor that can be mopped easily is better than a carpeted area.
Some providers allow children free access to the art shelves.
Others prefer to set out a limited supply of materials on the table, or at the easel, for that day's art exploration. Either way, the art center should be accessible throughout the day for little creative artists. Don't worry too much about the messes. Overreacting may inhibit a child's desire to create or even approach the art center. Enlist all of the children's help at the end of the day to assist in art center clean-up.
