1: Find jeans that you hate. I used old bell bottoms
2: Make the Legs skinny if needed
3: Cut the part you took in from the leg off with shears so it wont fray
4: Slash the legs using a razor or box cuter put cardboard in the legs so you dont go all the way through repeat on both sides but stager the slits so you dont cut a leg off of the jeans
5: So you are done but no quite yet. Through them in the wash until desired shredyness is achieved.
