This is a pair of black jeans I've made modifications to. The patches you see here were made by taking iron-on elbow patches, sewing a piece of fabric to them, ironing them on, and then sewing them into place. This was all done by hand. The two knee paches are purposely at different heights, so that one covers my knee while standing while the other does so while seated. There are two more pictures in this series, depicting the back and the strap on the left side.
