Using textile production in Postclassic Western Mesoamerica as a case study, this article explores how to differentiate low levels of craft production caused by household provisioning from low levels of craft production due to market reliance and regional specialization. I use a sample of 52 excavated site/phase components to establish baselines for the intensity of production and to evaluate whether participation in the market allowed craftspeople in some regions to underproduce textiles relative to local needs. Highland and lowland sites have comparable low frequencies of spindle whorls during the Early Postclassic, which I interpret as characteristic of household self-sufficiency. Whorl frequencies increase above this baseline earlier and to a higher degree in lowland sites than in highland sites. During the Late Postclassic, some regions may have formed pairs of over- and underproduction zones linked by the market. Because of changes in spinning technology, it is not possible to extrapolate the results of this study to earlier time periods. I then present data from Calixtlahuaca as an example of how macroregional data can be used to interpret craft production at a particular site. Textile production at Calixtlahuaca was generally low, but this was more likely a function of a strong dependence on maguey fiber, rather than underproduction caused by a reliance on the market.
