Most of us “could use more storage.”  In the majority of cases, though, it’s not space we’re lacking, per se, but ways to utilize that space.  One method I have found very helpful is to make use of the insides of my cabinet doors (particularly in the kitchen).  Here is an example: these are the insides of the doors to the cabinet below my kitchen sink.

(Ignore the paint spray.  We used a sprayer — well, mostly my sweet hubby did — to paint the exteriors of our cabinets red.  We’ve not gotten around to scraping the overspray off of the interiors.)

I simply attached Command hooks to the appropriate places, then hung these items up.  Pot holders (hot pads) are another thing I find handy to hang.  Inside an upper cabinet door beside the stove, they’re always within reach.

I use the inside of my pantry door, too, and hang aprons (in two rows — a lower row of hooks for my little girls’ aprons and an upper row for mine).

How do you make use of hidden space?
