Step 1

Prewash your fabric. Dry it in the dryer to shrink it as much as it wants to shrink. Press it as necessary.

Step 2

Print out the pattern page with the size you want to make and cut out the paper pattern piece.


 
 

 
 

Step 3

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.

Step 4

Stack fabric pieces as follows:

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.

Step 5

Stack lining fabric right sides together (if applicable); pin along centre front edge. Stitch as in step 4.

Step 6

Once stitched, open the mask so you can see the right side of the fabric on each.


 
 

 
 

Step 7

Align the top edges with right sides of outer fabric and lining fabric facing each other. Pin in place being careful to lay the centre-line seams facing away from each other to reduce bulk.

Step 8

Stitch along top edge with ¼” seam allowance.


 
 

 
 

Step 9

Align the bottom edges and pin in place with centre line seams facing away from each other, consistent with step 8.

Step 10

Stitch along bottom edge with ¼” seam allowance.
Image

 
 

 
 

Step 11

Align prepared wire at the centre seam allowance at the top of the mask and hand stitch to the seam allowance as close to the stitching line as possible. Stitch at each end of the wire, as close to the stitching line as possible while still being in the seam allowance.

Step 12

Starting at the bottom and at one of the open sides, little by little, gently draw the bottom edge of the mask through the opening. Once you have that out to the right side, locate the wire and very carefully guide it through the same opening.

Step 13

Finish turning the mask right side out.

Step 14

At the top edge, top stitch next to the wire to keep it in place. Be very careful not to hit the wire with the needle.

Step 15

Turn side seam allowance into the mask and place a pin in the middle of each seam.
Image

 
 

 
 

Step 16

Mark elastic ½” from each end. That is how much will be inside the mask. Attach a piece of elastic to the top and the bottom in the side seam, on one side of the mask only and stitch in place. For an adult, the top should be cut to about 13” and the bottom to about 11-1/2” (raw measurement).

Step 17

Pin the elastic to the other side seam at top and bottom being careful not to twist the elastic.

Image
 
 

 
 

Step 18

Carefully try the mask on and adjust the elastic to make it comfortable to you.


 
 

 
 

Step 19

Stitch elastic in place and top stitch sides closed.
Image

 
 

 
 

Step 20

Top stitch bottom edge of mask. The mask is complete.

Important Notes

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.
