Prewash your fabric. Dry it in the dryer to shrink it as much as it wants to shrink. Press it as necessary.
Align the pattern piece with the grain of the fabric. Cut out the pattern pieces as follows:
a. Cut 2 of the outer fabric (this may be a printed fabric, either a quilting fabric or flannelette. You can use muslin if you like. It should be 100% cotton)
b. Cut 2 of the lining fabric (This can be unbleached cotton muslin, pillow ticking or other 100% cotton fabric)
c. Cut 2 of non-woven interfacing.
place one layer of non-woven interfacing, two layers of outer fabric right sides together and another layer of non-woven interfacing. Carefully align the centre front edges and pin them in place. Stitch along the centre front seam, using a ¼” (6mm) seam allowance. You can do this either with a sewing machine or with a serger.
Wearing a mask is not a guarantee that you will not get sick. Viruses can transmit through the eyes and tiny viral particles (known as aerosols) can penetrate masks. However, masks are effective at capturing droplets, which is one main transmission route of coronavirus. Some studies have estimated a roughly five-fold protection versus no barrier at all. Other studies’ numbers were lower.
Tests have shown that masks using a layer of non-woven interfacing are more effective than using fabric alone.
If you are likely to be in close contact with someone infected, a mask cuts the chance of the disease being passed on. If you are showing symptoms of coronavirus, or have been diagnosed, wearing a mask can also protect others. Masks are crucial for health and social care workers looking after patients and are also recommended for family members who need to care for someone who is ill; ideally both the patient and the caregiver should have a mask.
If you are just walking around town, a mask will probably make little difference.
Use and Care of Your Mask
• When wearing your mask outside your home, do not touch the mask or your face
• When you return home, remove the mask by the elastic straps taking care not to handle the fabric if possible.
• If possible, wash it immediately. This style of mask has a contour wire over the nose. To protect the wire from damage, we recommend that you hand wash the mask in a basin of hot soapy water, agitating it for 2 minutes. Dry it in the dryer.
• If you wear masks at work, it is recommended that you change your mask when it becomes damp. Have a Ziploc style plastic bag to store the used masks in. Remove the mask and place it in the bag; seal the bag; wipe the bag down with an appropriate cleanser. Wash your hands thoroughly with soap before putting on a fresh mask.
• When you wash your masks, wash the Ziploc bag in the hot soapy water and set it to air dry (or dry it with a clean cloth or paper towel).
• I recommend labeling your Ziploc bags to identify clean masks vs used masks.
• If you need to disinfect your mask but do not have time to wash it, you can place it in an oven reheated to 150 F for 15 minutes. Coronavirus can not survive at temperatures above 133 F.
