pinholes
Needle-made openings
Pinholes are tiny holes, as if made by a pin.
The term describes small perforations in fabric, paper, or other materials—often defects: The old curtains were full of pinholes.
A pinhole camera uses a tiny aperture instead of a lens to project an image.
Pinholes in plumbing or containers cause slow leaks that may go unnoticed.
