Hello Dorothy from Tenn!
I came on to answer your request as I ran across a neoprene blank pacifier holder yesterday. I went back to find it and could not remember where I had seen it. I went to the site I ordered theread from yesterday and no luck.
However, some clever ladies on www.Etsy.com have come up with some sewing ideas that you could possibly draw your own design from.
Good Luck with your project.
Joan
P.S. if I come across the blank pacifier holder again, will remember you and forward the information.
