Esty's pretty big in America, but I was surprised how few seem to know of it here in the UK, unless they're net addicts like myself. There is also a similar UK based org, called Folksy.
For this 'Favourite Etsy' I am featuring La Pomme, whose charming pillows, sachets and more are so original and classy. La Pomme uses lots of vintage materials too. Definitely going on our wedding register.
