Should I just let her keep it?

About a year ago I sent my mom a rug from my old apartment to keep in her garage for storage. I recently decided to use it in my nursery, and was going to go pick it up. I just came over to her house and I saw that she has it out in her living room now (she just put it there today).

Keep in mind rugs are not cheap... but I don’t want to be weird and make it seem like I suddenly want it because she’s using it... should I ask for it back or just let her keep it?
