DD7 and I are now sporting cute flowers, turtles, smileys, and ladybugs on our shoes. They came out so cute!!! We love them! We got our buttons from the craft department at
Walmart.
I put mine on a pair of Ocean State Job Lot generic clogs, and they worked just fine. DD has hers on her Airwalks (with diamond holes!!) and they still worked just fine, for those of you who were wondering. We also found a way to use the really CUTE and detailed rubber buttons from Walmart that didn't come with a shank (and only have the two holes in the middle for thread). We put the regular flat securing button, then two smaller flat buttons, THEN the rubber button. This gave it the needed room to allow it to go into the hole. They also fit on DD's Disney Crocs (I only have the Niles, so no real Crocs holes for me. LOL!), but we had to be extra careful not to damage the tops of Mickey's head with the buttons.
Sooooo.... For the price of $9 (or 3 Jibbitz), we made 20 "shoe jewels" and have enough flat buttons to make several dozen more!
