Yeah! Plymouth Encore is great. I'm making an afghan/throw out of two colors right now. Feels soft, but can be washed. And LOTS of colors.
You might try: www.yarnware.com/web/yarnware/Yarnware.nsf/Yarn/PLYMOUTH_CLASSICS-ENCORE_Worsted!OpenDocument
If the link doesn't work, just go to Yarnware.com
I think they have many more colors available than most sites that list Plymouth Encore for sale.
Also, just google 'Plymouth Encore,' which will list sites, some ebay auctions, and other stuff about the yarn.
