The room we used was actually my husband's childhood room and had been ocean themed since my husband loves the ocean and sharks. We decided to stick with that theme but redo the whole room. I was inspired by some images I had seen on Pinterest and then just googled different fish and sketched their silhouettes onto paper. Then I cut them out and traced them onto the freshly painted walls with chalk and painted inside the chalk lines with a darker blue. It was a lot more time consuming than I thought it would be but so worth it.
