 From surviving Colonial crewelwork and written references such as letters, it is known that most projects were embroidered on linen.However, the preferred background fabrics were fustian (a twill fabric that generally had a linen warp with a cotton weft, though may have been all cotton) or dimity (which has fine vertical ribs and resembles fine corduroy).The range of wool colors that needleworkers in colonial New England could call upon were rather limited.
