From the desk of a professional knitter...

Here is some commissioned work from a fellow Etsy seller. She sent her own yarn, some measurements, and from that I knit 4 doggie sweaters. The photo isn't so hot but you can see the luster and the vivid colors. It is really pretty. It's a wool/ silk blend and it's not really next-to-the-skin soft, but it would be great for accessories and I bet it felts beautifully.
Dog-less dog sweaters always remind me of little crustaceans. Tee-hee!
