Pattern for crochet kitchen curtains?

Hi! Years ago my Mom made cotton thread crochet kitchen cafe curtains. I'm looking for a free pattern. Mom's were the pineapple design but I don't have a preference, just having trouble locating one of any kind. If you know of a crochet pattern leaflet or pattern book that I can buy (something I can find in a craft store like A.C.Moore or JoAnn's - possibly by Leisure Arts? They're a popular pattern company) I'd like to know that as well. I'm only interested in patterns using cotton thread, not yarn. If I get one, I'd be happy to share! Thanks for your time. Judi
