Pieces of silk fabric for mynewborn (Columbia city)

I am looking for multiple pieces (like 5) of small silk fabric, or it can be one large piece and I can cut it up. I need to set it behind my 11 week old’s head. He turns his head a lot when he is sleeping and has lost all his hair in one area, and laying on silk can help. Maybe you have an old shirt or dress or pillow case etc? Thanks! Would especially appreciate a drop off if possible but if not I can work out logistics
