I usually use the latex free bands when I make bows for my yorkie, they don't pull the hair out like regular bands. I buy them here www.ffps.com
Sometimes I use 30mm french barrettes. I buy them here http://www.etsy.com/listing/54132620...air-clips-30mm
You may be able to find them cheaper..I have not shopped around for them to much because I like there service.
