How do you make a finger sleeve?

To make a finger sleeve, start with a piece of elastic fabric or a stretchy material like neoprene. Cut it to the desired length and width, ensuring it can comfortably fit over your finger. Fold the material in half and sew the edges together, leaving one end open for your finger to slide in. Finally, turn it inside out for a smooth finish and ensure it fits snugly without being too tight.
