Every house needs one. A place where your pint-size Picassos can go to create their masterpieces. In our house it is usually the kitchen table or countertop. But we also like to work in mommy's art studio. My girls have their own cabinet stocked with all kinds of goodies. I picked it up at a neighborhood garage sale a few years ago and meant to paint it but never got around to it so it became the kiddo art closet. You don't have to go buy a piece of furniture. Look around and see if you have a book case, kitchen cabinet, rolling supply cart, filing cabinet, etc. that would work as a central location for all of the arts and crafts gear. They also have a little kid sized table and stools where they can get messy and mom won't freak out about them ruining the table finish!
I sorted supplies by general category and have them in easy to open containers so when my girls go off to create I'm not being asked to open something for them every 5 seconds. We have a ridiculous assortment of supplies but I used to be an art teacher so I can't help it. You'll find: paper (including white drawing, watercolor, colored construction paper, scrap paper, cardstock, and scraps of cardboard) clay, play-doh + tools, paints, markers, colored pencils, watercolor pencils, oil pastels, chalk pastels, craft foam sundries, pipe cleaners, yarn, googly eyes of assorted sizes, pom-pons, feathers, stamps, sequins, popsicle sticks, glue dots (fabulous!), Elmer's glue, glue sticks, glitter glue (very popular), stickers, etc.
When my girls (and their friends) go work in their space they come up with such creative ideas and have so much fun. They spend so much time in school doing structured activities and cookie-cutter art projects, I think it is important that every child has a space where they can invent and experiment with new materials and explore art in a safe and non-judgmental environment. If you read my previous post, I think it is just as important for us mommies to have a space like that as well!
