Marilyn, a frequent contributor to the comments and embroiderer on the jacket as well as a student of Japanese embroidery, recently asked me if any weaving was going on in Plymouth Colony as early as the 1620s.
The answer is no, we have no evidence that any was and lots of evidence that there was no fiber processing or textile production happening in Plymouth Colony until the late 1630s. There are several reasons why not, mostly that the point of having a colony was for it to provide raw materials and a market for finished goods to the mother country. The Plymouth colonists were under agreement to work for the betterment of the merchants who put up the seed money for the colony, not to become self-sufficient.
Many people expect that these colonial foremothers were self-sufficient, though, especially in a textile sort of way. That whole myth (which annoyingly has a grain of truth in that some colonial housewives in some places at some times were doing it all) is explored and explained in Laurel Thatcher Ulrich’s The Age of Homespun. I “reviewed” and recommended it last summer, August 19 to be exact (thanks, Lyn). Maybe it isn’t beach reading but it is well worth a look.
