Back in the 70's I had what seemed like a couple miles of one particular fabric,royal blue with mini white flowers. I made a skirt, then cut some into strips and knit a pull over vest to match.
I've seen kits in Walmart for knit purses or beanie hats made with cut fabric strips. I think the fabric was already cut. If I dig around in my stash, I probably bought 1 or 2 of them, but have never made them.
