I'm at a lost with a nursery/ baby shower theme since there isn't much for a boy that's in my taste.

We want it rustic, but not with deer, kind of like cow skull rustic-old western type. Pinterest has all girl things for this type of category so it's getting frustrating. Any ideas on what I can decor wise, what I would even call this?! Honestly any help and ideas will help so much! I am not creative at all lol.
