And that's it! You're on your way to creating an awesome and inventive makerspace for kids.
My one final pro-tip: Keep out. While it's tempting to assign them Pinterest-worthy craft projects and to hover as they slap a little too much glue on their homemade popsicle stick creations, avoid the urge to better their literal houses of cards. They'll learn far more if they're the ones calling the shots (and holding the glue gun.)
