I have been hanging on to some sweaters for several years not because I love wearing them but because I love the color combination and pattern. So I have cut one up, developed a pattern and reconstructed it into an over-the-shoulder bag. Complete with interior pockets. The strap was recycled from another purse that I use as a clutch.
I am tweeking the designs for a shoulder bag as well as a clutch. They will be on etsy.com soon.
