This idea is the best one I've come across in a long time! We have a lot of art/craft supplies because it's great to have on hand for activities for the kids. The frustration I always have is how to keep it organized. I basically had a bin for all the paint stuff that I had in one spot, then a tin for all crayons and that was in another spot and a place for papers, etc. It was all organized but not in one place. This idea keeps it all in one place and I am just so happy with this system!
Ben bought me the tool caddy (I think that's what they call them) at Home Depot and we have dozens of 5-gallon buckets because that's how I buy my laundry detergent. Just slide the caddy over the bucket and voila! Then you can start placing things in the many dividers and pockets. I did two, one for the kids drawing and card making stuff and another for their paint supplies.
Inside the bucket for the drawing supplies are the tracing, drawing and construction papers, container of crayons and coloring books. On the outside I put markers, pencils, pens, tape, pipe cleaners, tape, stickers, rulers, etc. For the second bucket of paint supplies I put the painting smocks I make the younger ones wear and the paint cups (everyone with kids should own these! I love them!) with bottles of refill paint. On the outside I put the brushes, paper, more paint bottles and glitter paints.
This had been working really well. I store the buckets in the bottom of the closet and then when it's time for one of these activities just pull out the bucket and it's all there. So easy, and so organized! I think the caddy cost about $6 so it's inexpensive too!
