Some have mastered the art and are now famous. Authentic Hopi Kachina dolls are expensive and limited compared to imitations. A full figure doll is considered to have all body parts carved, and is considered the standard. Full figure dolls are usually carved with more details and are priced higher than sculptures. Sculptures have only been around for a short while.
Sculptures are faster to carve as compared to a full figure doll.
On sculptures you may carve several dolls figures on one piece of wood and they are normally taller. Majority of the young generation now carve sculptures. A one piece doll is referred to as one whole kachina with no attachments. All body and other parts are carved from the same wood. These are more time consuming and requires a lot of patience, some carvers are now starting to use machinery to carve, it cuts down the carving by a third.
