I had grandiose plans of built in cabinets and drawers and counters, oh my! I was trying the think of a way to either convince my husband to spend the money on cabinets or get him to help me build them, when (after hearing me complain about my problem) he said, "Brenda, just get a few of those plastic cabinets on wheels like we have in our closets." At first, I thought, "No, it can't possibly be that simple," but the more I thought about it the more I liked the idea. A Mobile Craft Room!! I can organize my craft supplies to my hearts content, turn the dining room into a craft room, then when guests come over to eat I can just wheel them on out of there. These containers make great craft organizers.
So that is what I've done. Of course, one word of advice...
Now that your crafts supplies are nice and neatly organized, your kids are going to notice them more and want to use them. My suggestion is get one just for the kids and put in supplies that they can use on their own without your supervision. Believe me, they will be hit with inspiration many times a day and just have to get in there and make their ideas come to life. Let them decorate their own rolling cabinet so they know which one is theirs.
Some good supplies to include are, depending on age, colorful construction paper, coloring books, crayons, markers, safety scissors, glue sticks, tape, stickers--things that you don't mind refilling often and that are cheap. It will be worth it when your child comes walking in the room to show you their craft they made all by themselves.
