The first major project I decided to try was a purse, from this episode of Knitty Gritty. I made some changes, though: no pattern, just a free-hand "image," and wooden-like handles opposed to knitted handles. I used Lion's Brand Wool in three different colors.
I'd never used double-knitting before, or felting, so it was an adventure. And I really like the results!
Finished purse, ta-da.
I wish it were a little bigger. And that I'd made the closures a little more secure. I love using this purse, but it's difficult to carry everything I'd like.
