Paisley is a droplet-shaped vegetable motif of Indian or Persian origin. The pattern is sometimes called "Persian pickles" by American traditionalists, especially quiltmakers, and "Welsh pears" in Welsh textiles as far back as 1888.
Imports from the East India Company in the first half of the 17th century made paisley and other Indian patterns popular, and the Company was unable to import enough to meet the demand.
And now for a bit of social history, which I always find interesting ....
In the 19th Century European production of paisley increased, particularly in the Scottish town from which the pattern takes its modern name. Soldiers returning from the colonies brought home cashmere wool shawls from India, and the East India Company imported more. The design was copied from the costly silk and wool Kashmir shawls and adapted for use on handlooms.From roughly 1800 to 1850, the weavers of the town of Paisley in Renfrewshire, Scotland, became the foremost producers of these shawls, and so this pattern got called after the town they were made.
Obviously, if I'd had loads of Cashmere shawls lying around the place, I might of known all this!
Anyway, I am gonna now call it the 'Persian Pickle Pattern' as that sounds cooler than Paisley!
