I noticed it when I was sorting laundry. In the same place on the seat of all my favorite pants. I took a pair out to the garage and looked at my saddle. When I crashed this fall, I scuffed up one of the rivets on my saddle. It's too far out to the side for me to feel. Apparently not too far out to abrade holes in my pants. I got some fine grit sandpaper and smoothed it off. I guess I'm jeans shopping this weekend.
