This is more of a recommendation, because I've seen several posts here and on the Discord about coming up with 30-50 objects for this exercise. I just took a look around 3 different rooms in my house -- a living room, a bedroom, and a bathroom. Not counting things that were "nearly identical" (ie same as something else but a variation with some slight differences), I was easily able to come up with 30 different objects in each room. With the variations and duplicates, even 50 would be a low end of what was in each room. So if you need ideas, take a look around you. You're bound to find way more ideas than you need!
