My house collects dust and dog hair. My dog Brutus collects fabric scraps and threads. DH collects shot glasses. I also collect key chains from airports where family and friends have traveled. I also have some with sewing/quilting notions attached. I have a key chain that is with me all the time with a measuring tape. I give those kinds of key chains to my friends also who like to sew or just need a measuring tape at some time.
