Here is a picture of a quilt I included a ghost in.

I had been living in a converted "Home for wayward Girls" and was pinning three sections together in a long hallway. I felt a cool breeze, turned, and there was a nun there, in big clunky shoes. She blessed me, then headed down the hall. I took the pins out of my mouth to thank her, but she just disappeared through the closed door at the end of the hall.
There are many people living and working at the condos there who have seen them, in different part of the buildings.
