Jill works mainly in 1:12 scale although she also creates some larger dolls up to 9 inches tall. Her dolls have porcelain heads and pewter bodies strung through with twisted steel wire at the joints. This gives them considerable flexibility to stand or sit or adopt other poses. (They will stand without support.)
Her early dolls made in partnership with Sukey Erland were marketed under the Bennett and Erland mark (B.E.). In the early years of the emerging dolls house market they strove to create reproducible dolls which were not expensive.
When her partner Sukey left London, Jill joined up with Jamie Carrington and their partnership, J Designs, made dolls with porcelain heads and metal bodies. J Designs is now a company creating 1:24 scale dolls, run by Jill's daughter.
For the last fifteen years, Jill Bennett has made only original one off designs under her own name.
