This was the article carrier designed and built for Sunshine, my first dog. It is now well worn from use. She used it while earning her UD, UDX, and OTCH.
I have since built several for friends just like it, and several variations as well.
One thing they all have in common is a specific location for each article and a free flow of air around each article. This way you never have to air the articles, they are always airing out and ready to go. In the ring you can easily find a matched pair with out digging through a tangled jumble of articles.
