This is a former ladies' fair isle cardigan. I felted (shrunk) it, resized the sides, and sewed up where the button placket used to be.
I added a couple of decorative buttons at the neck opening.
Good to go in under 30 minutes, and loads cheaper than store a bought wool sweater. I'm sure this is what our grandmothers and their grandmothers did when something wore out in the family :) What are you making over these days?
