The mask that we are going to create has three different layers:


You will need:
When choosing a cotton fabric, it's important to check that the threads that compose it are tight enough to act as a barrier.
A simple and efficient test is to observe if the sunlight is passing through it. If a lot of light passes through, then select a fabric which seems more opaque to it, because the meshes that compose it are tighter.


The standard sewing pattern requires tracing a 20x20cm / 7.9x7.9in square in your two cotton fabrics. The seam allowances are included in these dimensions.
You can use our standard sewing patterns. Print them in full page then cut.


Use a zigzag stitch on all edges.
Fold over 1cm / 0.4in.
Sew the top edge with a straight stitch for a cleaner result. This will be our mask opening, it will be used to insert the filter inside.


Once the two cotton squares are cut, mark the folding lines A1, A2, B1, B2 on them.
Fold the points A1 over A2.
Do the same thing with B1 over B2.
Pin it.


Add the elastics:
Stack the two squares on top of each other.
Pin it.


Sew the edges.
Attention, you must not sew the top edge.
Start on one side, move to the bottom edge and finish on the other side.


Turn the mask upside, check that the seams hold correctly.
Sew a seam all along at 1cm / 0.4in from the edge in order to keep the fabric layers together during washes. Start this seam on the top edge at 2cm / 0.8in from the right or left edge. Follow the border around and finish on the other side at 2cm / 0.8in from the edge.
This way we keep a large opening to slide in our filter, which will be well maintained.


Well done! You can now insert your filter in the opening.
You now have a great personalized mask, your new fashion accessory!
