Just clearing out dd2's wardrobe and she has two denim pinafores and a denim skirt she has outgrown. I am considering cutting them into squares and making a patchwork skirt. I wondered about making it with the frayed edges on the outside, just as an experiment, but am wondering if it will fray right back to the seams and therefore fall apart when washed? Anyone any experience of denim doing this - would I be mad trying to do it without overlocking the edges first?
