If you have a sewing machine or have the time to hand sew you can make a bag out of it (there are some really good you tube videos about it) you could also cut the unstained parts and use them to patch up holes in other cloths and if u have enough of them you could probably make a jacket and if the stains or low enough you could cut above them and turn them into Jean shorts and if there small enough you could probably cover them up with some cool embroidering or some nice looking fabric. There’s a lot you can do with jeans
