I was creative and did my own little DIY project to help wrangle in my flip flop situation.
Before I just heaved all my footwear into a basket in my closet. While it kept them contained it was a pain matching them up again when I wanted to wear them. It was like matching socks from the dryer-so not fun.
I did a little searching on the webs to get ideas about how other people handled their shoes but nothing really interested me and I didn't really want to buy something. So I cast about my house for what I already owned and inspiration struck!
I present my flip flop storage:
Cut up the cardboard. I just did some guesstimating cutting. No real measuring involved unless you want to be more precise. Though I did figure out that I only needed 3 pieces in each size. Oy.
Cut notches into the cardboard where they will fit together. I cut the pieces to a little past halfway for each.
Fit cardboard pieces together to make the grid. You position the notches/cuts so one set is at the top and the other is on the bottom and they just slide into each other.
Wrangle the completed grid into the basket and bask in your brilliance.
You can tell that there were no rulers or measuring tape used by the un-uniformed spaces produced. But once the flip flops were in, it all worked out.
