My most strenuous objection is when someone calls a crocheted afghan a "quilt" - a total confusion of terms.
Ugggh. HAte that. The PBS ad where the carpenter dudes, Norm I think, and some of the THis Old House cast, talk about watching the quilt shows, and hold up a crocheted afghan -- never fails to set my teeth on edge. That would be like Nancy and Pokey holding up the "woodwork" they've crafted out of sheet metal -- totally wrong genre.
The origins of quilting are interesting to try to figure out. My grandmother, who was born in China, always claimed that the traditional Chinese layered clothing was the true origins. While my parents, who lived in Kenya for a long time, point to the pieced fabric works of some of the tribes as a possible source for patchwork origins. I say it rose independently from multiple sources, with varied approaches and aesthetics.
