Your dolls and their clothes are beautiful. Have you thought of opening an ETSY shop or selling on e-Bay? If you don't want to sell that way do you have another venue? Is there a local store (perhaps a fabric store whose fabrics you have used for the dolls and clothes) where you could display a few dolls on a trial basis? I think there is the potential for making some good $$ based these pictures but only if you can get into a place where it would be seen by people who would buy custom work like this.
As an alternative, what about going into your local fabric store(s) and showing the dolls and clothes and offering to do classes teaching how it's done?
