Design school for a non-design student?

Hey I’m going into my senior year studying politics, with an art history minor. I have some museum experience, but I’m getting bored with it and would like to take a more hands on and creative approach. That being said I’ve always been intrigued with design, but was never sure how to involve myself. I have no formal background, but its something I would like to pursue while I have the chance.

My questions is really where to start and where to get experience, before committing to a pricey graduate program (hypothetically considering I have never studied design before). Any advice or suggestion on how to get involved in the design community and figure out if its for me would be greatly appreciated.
