The hardware and instructions came from Country Brook Design. They carry everything you need to make collars, leashes, etc.
My daughter suggested trying to make an inter-changeable collar. After giving it lots of thought, I bought some 1" black webbing and 2 rolls of 7/8" ribbon. I made the collar base using the instructions from Country Brook but added velcro in 3 spots on the collar, one on either end and one in the middle. I sewed 2 pieces of velcro at either end and one in the middle. I cut the ribbon to the length adding about 1/2" to each end to turn under and add the velcro. The one attached to the collar in the photo below matches her new coat ;)
Here's a photo of the first two "covers" that I've made. I also have a purple tiger print for football season too! Making the collar this way will not only save me money but will also allow Penny to have "party collars" just like I have my "party glasses". (I have a glass for almost every occasion and love them!)
These are incredibly easy to make and will save a TON of money!
A huge "thank you" to my daughter for the idea!
