My niece, MiMi, posted on Facebook a site that has some wonderfully simple DIY suggestions. Here is the site: http://diyhshp.blogspot.com/2013/08/50-insanely-clever-organizing-ideas.html
And here are a few cool ideas that followed me home.
Pegged to the inside of the cabinet door -- This one I did right away and love how simple it is
Shower baskets for the kiddy car stuff we all carry
Empty baby wipe containers -- great storage boxes
This one is for the journalers out there --- glue a closeable envelope to the inside of your journal. Keeps the extras organized and in one place.
