One of my first knitting projects was a poncho. Made out of novelty-like yarn, it was warm, but too short for my upper body and my neck was always cold while wearing it, so I never used it.
The poncho spent 8+ years in a closet. It has memories attached to it so I could never get rid of it. Last year I cleaned out some cupboards, like I want to do more often, and decided that I would give the poncho a new life as a pillow.
So I seamed up the sides to make it into a square, trimmed the sides and secured the edges with bias tape and hand-sewed the bottom and the top closed. Now I have a pillow that I love and goes well with our living room!
