Help! I don’t know the reason but my son seems to have a talent of ruining his jeans fast. The fastest record is two weeks. The rest of the jeans still look brand new except for the knee areas. The two torn areas make the jeans look so dingy I have to throw away lots of pants due to this reason. Is there anyway to mend the pants without looking dingy or strange. I’m sure I’m not alone on this issue. I’d appreciate for any advice. Thanks!
