How do you make a bassinet sheet?

To make a bassinet sheet, start by measuring the dimensions of the bassinet mattress, typically around 30 inches by 15 inches. Choose a soft, breathable fabric like cotton and cut a piece that is slightly larger than the mattress to allow for seams and fitting. Sew elastic around the edges to create a fitted sheet that can stretch over the mattress securely. Finally, finish the edges with a hem for a neat appearance and to prevent fraying.
