I used to do this to my girls' jeans after school let out. Great way to boost the summer wardrobe for next to nothing! Transform an old pair of jeans into adorable summer shorts using bias tape. Instructions on the site.
squares + sew patchwork + cut out a-line shape = very cute skirt! This gives me an idea for using scraps to make skirts & dresses for little girls. Use smaller squares & simply cut out pattern on the diagonal.
