DIY Cloth Face Mask


UPDATE 4

Hey mask makers! You rock! Sorry to disappear for a week but I was helping get our local community mask sewing project off the ground (western North Carolina). I've added a Mask 1 pattern PDF (reg size) with a GRID on it, at last. Also some new informative links related to cloth mask effectiveness and other relevant topics. Lastly, I've added a section about FILTERS. Keep sewing and keep safe!

UPDATE 3
Child size pattern added, problem with large size pattern PDF solved, added some more measurements to the wire and elastic supply list, added a whole section on filter options in the research notes. Tomorrow I will add a new step at the end, with a list of community coordinated mask sewing calls. Medical facilities asking for DIY help to alleviate short supplies across the US and elsewhere.

UPDATE 2
Holy moly, the DIY face mask world is blowing up. See #millionmaskchallenge on twitter. Some of the info being shared is incorrect, at least according to what I've been looking at for the last 2 weeks. But some of it is useful. I am trying to compile relevant new info in the research notes at the end.

UPDATE
Hey folks, thanks for reading. I just shared the research links I used in the final step, if you want to come to your own conclusions. I have also added a simpler version of the pattern (Mask 2) with no filter pocket, as well as a larger size option (in Step 1 files). I will continue to update this pattern and info as I can. Working on a kid size one next. Stay safe!

Why You Should Make (and wear!) Your Own Cloth Face Mask (and how do it)

With highly contagious coronavirus (COVID19) rapidly spreading throughout the world, many people are shopping for surgical masks to protect against this dangerous disease.

The sudden increase in demand for “Personal Protective Equipment” (PPE) and the interrupted supply lines in China have led to a critical shortage of small particle filtering face masks (N-95s) and fitted rectangular sneeze guards (“surgical masks”).

News reports, appropriately seeking to reserve limited supplies of these disposable items for medical institutions, have been asking people not to purchase these items. Public officials have been quoted suggesting – inaccurately – that face coverings can’t help prevent the spread of this new virus.

The truth is more complicated:

COVID19 is spread from person-to-person in droplets of moisture, mucus and saliva from people with infections. Coughing, sneezing, and even normal breathing put these virus particles into the air. One sneeze can put out thousands of droplets.

People standing less than 6 feet away may become covered with these virus particles while they are still in the air. After the droplets fall, the virus particles can remain active for up to nine days.

Infection occurs when someone breathes in airborne droplets, or when they touch their mouth, nose or eyes with hands covered in virus particles that have fallen out of the air onto counters, hand rails, floors or other surfaces.

Wearing a face mask stops people from becoming infected in two ways:

1) By blocking most airborne droplets filled with virus from being inhaled

2) By stopping the wearer from touching their own mouths and noses.

Studies have shown that medical professional using surgical face masks correctly get 80% fewer infections than those who don’t.

So why the mixed messages?

First, because the protection only comes when the masks are used properly. They must be put on clean, taken off carefully, and paired with rigorous hand washing, and the discipline not to touch the face.

Second, because gaps around the masks and between fibers, even in commercial surgical masks, are too large to block all viruses. Sneeze and cough droplets are usually between 7 and 100 microns. Surgical masks and some cloth masks will block 7 micron particles. The COVID19 virus particles are 0.06 to 0.14 microns.

So why should you make your own face masks?

1) In the event you become sick, having a supply of masks at home will give some level of protection to friends and family while you seek medical advice. It will certainly be better than no mask at all (see research notes).

2) By making your own, and hopefully for family and friends, you will be decreasing demand on limited supplies of industrially manufactured, disposables, which are desperately needed by hospitals and nursing homes.

3) These comfortable, curved shaped masks rest closer to the face, with fewer gaps, than rectangular surgical masks.

4) Our homemade designs are washable, making them environmentally friendly.

Supplies:

Mask 1 is fitted, with 2 layers of fabric and a pocket between them for an optional filter (see research links for info on filters). It is held on by elastic ear loops. Elastic can also be threaded to fit around the head.

Mask 2 is fitted, with 2 layers but no pocket, and is easier to make.

seam allowances are ¼” unless noted

MASK 1 & 2 supplies (child, regular and large size):

9" x 15" fabric outer layer
9" x 15" fabric lining layer
(3 regular or large size masks of either design, can be made from 1/4 yard (9") of 45” wide fabric)
3” piece of soft wire (this can be decorative wire as shown, or picture wire, or even a paper clip if that's all you can find)
approx. 22” of elastic cord (child size length 10", regular size length 11-12", large size length 13")

WHAT KIND OF FABRIC?
You can choose any tightly woven cotton or cotton/poly fabric you like. Hold it up to the light to see how tight the weave is. Use the same fabric for outer and lining if you want, or use different ones to help you remember which side is clean and which dirty.

The research (see links at the end) shows 100% cotton having some effectiveness. Cotton/polyester blends may have additional properties of repelling water, making them better barriers to keep droplets from soaking through outer layers.

Don't use stretchy, sequined or velvet material.

Wash all fabrics before sewing to pre-shrink, and to assure you are working with the most sanitary materials possible.

Step 1: Pattern, Cut, Center Seam

Print out PDF paper pattern piece(s) at actual size on 8.5” x 11” paper. For MASK 1 print file called "Mask 1 reg size pattern". It has 2 pieces: A (outer) and B (lining) . For MASK 2, print either "Mask 2 reg size pattern" or "Mask 2 large pattern" or "Mask 2 child pattern". It just has one piece. At this time I don't have a large or child size pattern for a Mask 1. Will work on that. Cut out the paper pattern pieces.

For those without a printer - I will upload a gridded image soon so you can draw it yourself, meanwhile do what you can with the measurements:
Mask 1 piece A is 6 3/8" h x 5.25" w. at the bottom B is 6 3/8" h x 4.25" w at the bottom
Mask 2 child is 5.25" h x 4 7/8" w and the bottom
Mask 2 regular is 6.25" h x 5.5" w at the bottom
Mask 2 large is 6.75" h x 6" w at the bottom

Fold your fabrics right sides together.

MASK 1

Pin pattern(s) to folded fabrics and cut two A and two B. Transfer the 2 dots from pattern onto the two A pieces on wrong side of fabric. Pencil a line between them lightly on each piece.

MASK 2

Pin pattern piece to folded fabrics (outer and lining). Cut 4.

Sew center curves of outer layers, right sides together. Sew center curves of lining layers, right sides together. Clip the curved seam at about ½” intervals but not down to the seam.

Step 2: MASK 1 Sides, Sleeves for Elastic

For MASK 1 (with pocket)

Fold straight sides of lining fabric toward wrong side, and sew fold down with straight stitch.

On outer layer sides, fold top and bottom corners down, using the dotted lines on pattern and the transferred dots as guides. Pin. Fold raw edge over and pin. Ironing helps keep this in place. Stitch along all the 3 folds on each side, 1/8” from fold.

Make the sleeves for the elastic - With wrong side up, fold angled, stitched ends of outer layer up to the pencil line. Stitch down.

Step 3: MASK 1 Connect Layers, Elastic

Lay inner layer over outer layer, right sides facing in. Sew the top edge and the bottom edge. Clip curved seam.

Turn right side out. Top stitch the top and bottom seams, 1/8” from edge. This will assure both layers stay in place during laundering.

Feed elastic through the sleeves (approx. 11” per side). A wire needle or small safety pin can help feed it through.

Step 4: MASK 1 Nose Wire, Elastic, Filter

Make a channel to hold the nose wire by stitching a line 1/4” from the top stitch line, echoing the curve (2” on each side). Slide a 3”ish piece of wire into the slot created (loop the ends first with pliers if they are sharp). Sew the ends of the channel closed.

Tie ends of elastic into loops and fit mask to your head by tucking loops behind ears. Adjust knots as needed. It should fit snugly but not pull on your ears. If desired, you can make the elastic go around the back of the head. Don't cut the elastic in half. Feed each end of the 16" length through the sleeves in a U shape. Tie together and fit mask. Adjust knot as needed for snug fit.

Bend the wire to fit snugly over the bridge of your nose.

Optional: If you have a suitable filter material, you can increase the filtering capacity by slipping this material into the pocket between the outer layer and the lining. Cut whatever filter material to fit as needed. See research notes for more about what might be suitable.

Step 5: MASK 2 Instructions

For MASK 2 (easier, no pocket)

Pin right sides of outer and lining layers facing each other. Sew all the way around the edge, except for a 1.5" gap on the bottom edge. Turn right side out and press.

Note - the pointy end of an ironing board is the perfect size and shape to press these masks on.

Sew the wire channel, 1/2" down from edge and 2" to each side of the center seam. See picture.

Slide the wire through the turning hole, into the wire channel. Stitch the ends of the channel closed so it won't move around when washed.

Top stitch 1/8" around the entire mask, closing up the turning hole as you do.Be careful of the wire. You can skip that section of top stitching if there isn't enough room to go above the wire.

Lay mask with lining side up on table and fold 1" of each end of the mask toward the center. Pin and sew, making the elastic channels.

See Step 4 of MASK 1 for how to thread the elastic.

Step 6: Conclusion 

Conclusion:

We recommend making 3 masks per person: one to wear, one in the wash, one for a spare or to share. Remember, always remove the mask carefully. Do not reach under the mask with dirty hands. Touch dirty to dirty, clean to clean. Wash your hands and face immediately after removing mask. For best results in cleaning masks - immediately upon removing, spray the front and back with hydrogen peroxide to kill germs, then wash in soap and hot water.
