Creative Fiasco is run by Sabra Summers, she makes awesome collars that are pre-made and you can inquire about custom collars! Wally got his Superman Collar from her 5 months ago, and it hasn't frayed at all. It's still in perfect condition!
We're now ordering a custom collar for Tiki of Wonder Woman (since there are no Wonder Woman fabrics on the market that I like, she made a custom design for us).
