Using Wood Pallets: Make a bed frame! Just sand the pallets to remove splinters, and then paint and varnish to seal it all in if you so wish! And as an added bonus, you can use the underside for storage.
What to do with those huge Christmas popcorn bins! There is always something that needs storage containers. Ex. kids toys like cars, leggos, blocks, barbies, or in older kids, like video games, or small board games dominos, cards, jenga, things like that. Also crafts and projects, scrap fabrics, bday/anniv cards that you cant seem to throw away. Great storage for just about anything.
