This is a pair of Levi's 569 32 X 30. The legs were so wide, I wanted to give them more of a feminine feel with the visible mending.
Before I start any denim mend, I cut off all of the excess strings and fluff, leaving a clean denim edge. This often makes the rips appear much larger, so make sure not to cut your patches until you have cut away all of the damaged denim.
After cutting off all of the excess, I cut patches 1/2"- 3/4" larger than the hole you are repairing. Then, secure the patch by pinning all the way around the hole.
