I have so many random little trinkets (small paintings for my bathroom, jewellery dishes and even a little jewellery box shaped like a cushion with a cunty heel on top) — all of which were unexpected, slowly-collected finds at random thrift stores.
I second the previous comment about slow articulation. If you have the essentials, and are craving individual-niches — take your time :) which is prescriptive advice, but the effects of delayed gratification are like how paintings go up in a museum — with time, shuffling between here n there, and lots of patience
I also like going to winners or marshals or home sense for little strange things
