Flip Flop Back Straps

This is another- why didn't I think of that??  Seriously these Interchangeable Flip Flop Back Straps from Make It and Love It are so stinkin' cute and SO practical.  Love them!  Can't wait to make some for my 4 year old (he's a boy so there will be no bows) who also has trouble keeping his big boy flip flops on his feet.
