I would add other games according to themes as the year goes on. Let's say I have a container for storing the pegboard pegs. I might cut out a picture of the pegs in the catalog and then glue it to the label. Often, classroom supplies are ordered from these catalogs so the pictures are of the same exact supplies you have in the room. Activities have no right or wrong way of being done.
Children decide how to sculpt, collage, paint, and color.
This center definitely needs a sink or place to wash hands. I personally would keep back some of the above items for special occasions or for use with particular themes. I know I wouldn't want to play there. Collage materials are so much more appealing if they are separated into various containers rather than dumped all together. Lazy Susans are a great way to display what's available in the Art Center.
