There are lots of ways to make face masks and many of them don’t require sewing but here’s how I made mine: 

🌸 Cut two pieces of cotton fabric 24cm wide and 20cm high, and four pieces of ribbon or cord each 30cm long

🌸 Pin fabric right sides together with cord on inside at each corner

🌸 Sew around edge starting on a short side and leaving a gap when you finish back around on that side 

🌸 Turn through to right side using the gap you have left 

🌸 Make three folds lengthways, pin and sew each short side closing the gap and creating the pleats
