Aimee from Clones ‘N Clowns shows how to add leather knee patches to a pair of pants. This is a no-sew project, as she uses leather adhesive to attach the patches to the pants. If you wanted to stitch the patches down, you could rip open the inseam, stitch the patches, and then resew the inseam shut. Go to her tutorial.
