The markers were the easiest thing to find, but I could have done any number of things that would have fit into the container. I need to cut out the back of the container, so she can retrieve her markers by herself. She was getting so good, that she was able to put 2 in at a time.
When she isn't using her container, she loves to put markers and crayons in these Ikea stools. Like the container, they have a hole in the top and the red part lifts off. Unfortunately the stools are usually occupied by a three year old.
