Is there a place that I can take all my kids holey jeans?

I don't think that Goodwill stores will accept jeans/pants with holes in them, and I don't know where else I can take all of these jeans with holes in the knees etc. I've given some to my mom in law as she sometimes makes denim quilts, but I've got SO many that she can't use. I hate the thought of throwing them away. What do you all do with all of your old holey jeans?
