A friend of mine named Sue makes show bows for Yorkies . She has made a video on how exactly to make bows, and what products you need to buy etc.
I'm not exactly sure how much she sells the video's and or DVDs for but its reasonable. Her email is
doglady21@comcast.netand you can put BOW VIDEO in the subject line and she will let you know how to buy one of her video's if you ask her.
