Necessity being the mother of invention, (i.e. no clean shorts to wear on a beautiful sunny day), I took a pair of old jeans, marked a line in white gel pen about three fingers high from the top of the knee. Then with a pair of scissors i cut one leg off and then put that cut leg on top of the uncut leg to use as a guide to cut the second leg off. The idea for rolling them a little came from my boyfriend who asked to be credited on his input ;-) Free shorts! This would also work well with a pair of jeans have bicycle oil stains on them.
