Answer to "Wall mounting"Have you considered 3M Command Velcro hangers? Ace Hardware carries the large size which holds up to 10 pounds and they are very easy to take down. I use them for mounting dishes on wall... They come off easily (no residue.) http://solutions.3m.com/wps/portal/3M/en...
Answer to "How do I patch a hole in a pair of jeans?"Someone here is surely going to want to SEW the repair, so I'll address it. I say wear them till they are too big or ugly. If you have a machine, you need to take a razor blade or seam ripper and remove the belt loop if the rip is underneath it. Since the rip is above BOTH pockets, I assume it is not along the back seam. So look for the "zigZag" stitch vvvv, and make the stitch width as high as it will go. The stitch length should be fairly long too. Position the rip so both sides are held together under the sewing foot, and stitch. Reverse, stitch again. Takes 5 minutes...depending on rip size.
