Dress up plain flip flops with paracord. Use the same method that you'd use for a bracelet, but use the strap of the flip flop for the center. The tutorial in the attached link shows how to make them by completely removing the strap.
I snapped this photo of this sweet loving dog named "Pup" at the flea market, carrying his favorite stuffed toy. Pup was rescued from a group of men that were horribly abusing him, things I can't speak of, nor do I want to repeat. It amazes me how an animal can experience such horrors at the hands of careless people, yet learn to trust people once again. Sleep tight tonight, Pup.
