It's inevitable. You've finally figured out how to store their clothes, and the bulk of their toys, but they're growing up- and older kids start collections. So where will his 52 animal figurines go? On the above shelf complete with picket fence of course. See Cookie's solutions for other collections below...
And for those 547 rocks and shells...a 32 compartment drawer organizer will cost you just eight bucks at the Container Store and keep the flooding at bay.
What to do with 200 Pez Dispensers? Staple your favorite piece of fabric to fiberboard after sewing little loops of cotton tape to hold the dispensers. It's like a work of art.
Check out the rest of the collections over at Cookie and thanks to Rachel for the tip.
