An Ikea Hack custom train and activity table with TONS of storage. This is such an an EASY DIY project and a great way to get all of those toys up off the floor and organized once and for all! Maybe a Lego table and storage?
Of course I know how magnets work (ok, I kind of know how magnets work), but somehow they still seem a little bit like magic: these wonderful surfaces that things mysteriously stick to, seemingly in defiance of the law of gravity
Even in a tiny house - there's room for something like this - DIY Children Stove with Oven – Ikea Hack. Link is in a foreign language, but the picture shows it well. Cheap end table turned into toy stove. I would have loved this as a kid!
