i'm also trading http://www.sweetpetula.etsy.com/ a baby hat or sweater for some handmade soap and dog shampoo.
because most of the sellers on etsy are craftspeople (some sell vintage or craft supplies), we appreciate each other's work. there's a lot of trading going on. i initiate or agree to trades for supplies that go back into my work and items that i would normally be buying . right now i have a couple of lovely trades happening. beth at http://www.whorlingtides.etsy.com/ is trading me a selection of handspun yarn (i love her colours) for 1 of my hooked mats.
