Choose a pair of jeans you want to cut
Put them on and mark the desired shorts length with chalk or a fabric marker
Remove the jeans and lay them flat on a table
Measure both legs to make sure the marks are even
Add extra length if you want to hem or fray the edges
Cut one leg first along the marked line
Fold the jeans in half and use the first cut as a guide for the second leg
Cut the second leg to match
Try the shorts on and adjust the length if needed
Fold and sew a hem if you want a finished edge
Leave the edges raw if you want frayed shorts
Wash and dry the shorts to help the edges fray evenly
