Coolio Collar!
You know the REALLY cheapo collars? In like, department stores? Ok, well I went and bought one of those for about $3.99, and I already had glitter glue and rhinestones at home. I just.. went crazy! It's really fun to costumize your dog's collar.
I have also noticed that super glue is NOT the best glue to use on nylon-collar fabric. Gorilla glue is MUCH better. Have fun! :)
Editor's note: Thanks for the great idea for this decorative dog collar - and the tip about which glue to use!
