I recall the flour bags made of cotton,( in the 50's) my Mum made me petticoats and nickers from them. She bleached the writing out, then made the undergarments and added her own lace or embroidery stitches to make them pretty. I remember one set had lovely Dutch girls on it with windmills and she put blue Rickrack along the bottom of the petticoat, it was nice enough to wear on the outside, all the work she put into it!!
