Of course not all collections are particularly useful (we imagine these 'shoe-shaped' rocks don't see too much action) but for those that are we're curious, do you use them? Living in an apartment or small space we imagine it would be difficult to have a big group of objects that don't serve at least some type of purpose, but maybe it depends. So tell us! What's your collection? Is it composed of things you actually use?
