Making Masks at Home

There are two basic types of surgical masks- one that has elastic ear loops and one that has longer ties.  While the elastic is easier to put on and take off, the elastic can eventually irritate the ear over long-term usage so for comfort, the tie-back style is preferred. 

It is important to understand that a proper surgical mask has two elements to it that aid in protection: a fluid barrier, and a filter.  The outer layers of the mask are water-repellent, mostly to protect from splashes and bodily fluids during procedures, but it has been suggested that the water-repellency might also help prevent any droplets in the air from clinging to your mask. 

Then there is a filter inside to prevent particles, bacteria, and viruses passing through.  The CDC has recently revised its recommendations that all people should now wear cloth masks when in public, especially in situations in which it would be difficult to keep the proper distance of six feet between people, such as grocery stores and pharmacies. 

“Something is better than NOTHING!”

These days it’s all about risk mitigation

There are plenty of instructions for making knit masks roughly the shape of the N-95 respirator online; I have been making something closer to a surgical mask so I will present a method of making that kind of mask at home.  Please understand that these instructions are for informational purposes only, that I make no claim or warranty about any of its usefulness to prevent the spread of bacteria or viruses, or that following these instructions may help prevent the spread of COVID-19.

What you will need:

  • Material for your face mask- a piece 7 ½” x 14” long per mask
  • Soft aluminum wire for a nose bridge- 6 1/2” long
  • Elastic ear loops or woven ribbon or tape for head ties- two 7” elastic loops or four 15” ties
  • Optional filtration media

Choosing Material

A Cambridge University study found that basic cloth masks could filter 50% of viruses and bacteria, as compared to the 95% filtration rate achieved by N-95 respirators.  50% is certainly better than nothing so we are being encouraged to cover up in public. A website called SmartAirFilters makes the study a bit easier to understand, and concludes that, although other items provided better filtration rates, the overall comfort and breathability of pillowcases and cotton t-shirts made them the best choice for a DIY mask. If you wanted some level of fluid barrier like in a surgical mask, you could consider something lightweight and water resistant like Ottertex Ripstop from Fabric Wholesale Direct

Nose Bridge

N-95 respirator

If you look at an N-95 respirator you will notice it has a flat aluminum bridge across the nose; studying surgical masks you will also notice they have wire across the top.  These help the mask to conform to the shape of the nose and the upper face, creating a better seal. 

A nose wire helps seal the mask to your face.

Aluminum is best as it is soft and moldable, and won’t rust.  Without this wire there are significant gaps on either side of the nose through which unfiltered air and particles can pass easily.  My personal preference is a flat aluminum wire, like this one from Joann

I have also used a 1mm x 4mm flat aluminum wire from Michael’s.  If you can’t find flat wire, you could use soft round wire this this one from Home Depot


The mask can be fastened to the face using elastic loops cut to 7” lengths, like this from Joann

You could also use flat ribbon like this from Amazon.

Any kind of twill tape or ribbon or double fold bias binding can work, or you can make your own by cutting strips of fabric 15” long by 1” wide, folding them in half and sewing ¼” from the long edge, then turning them to the right side, like spaghetti straps.


To use a filtering layer is entirely your choice.  I cannot endorse any of them, but can point out a couple I have heard of.  Household HVAC filters with a minimum MERV-13 rating are supposed to be able to filter bacteria and viruses (nothing rated lower than 13), however I feel they may be a bit too stiff to conform around the face properly.  I haven’t tried it so I don’t know. There is also a company called Filti which makes washable household filters; they claim that their patent-pending nanofiber technology can filter viruses, and is washable.  They are selling their filter material on their website which can be found here.

Making your mask

  1. Print out and tape together the pattern.  Using the pattern, mark out your piece, and mark the notches or trace the fold lines using a tracing wheel.  If you have a selvedge, use that for one long side of your piece.  As sewers, our natural inclination is to want to finish the mask neatly, by sewing a seam right sides together and then turning, or perhaps by binding the edges with bias binding.  I have found, however, that the extra bulk and stiffness created with finishes like this prevent the mask from conforming with the shape of your face and it can have a tendency to sit away.  For this reason I prefer to use a serger or zig-zag stitch to finish the edges; it is softer and molds better.  If you don’t have a serger, and have a lot of time on your hands because you are confined to your house, you could also hand-finish them using a blanket stitch.
  2. Cut a length of wire 6 1/2″ long. Fold the rectangle in half lengthwise, wrong sides together.  If you choose to include filtration, sandwich your filtration layer between these two outside layers. If you have a zipper foot you could tuck the wire inside the fold and stitch alongside it, otherwise stitch a ¼” channel along the length of the fold.  Insert the wire into the channel.
Sew 1/4″ from the folded edge.
Or place the wire in the edge and use a zipper foot to sew it in.
  1. Refer to the pattern for pleating instructions- fold along fold line A and match it to placement line A. The pictures below show the pleat formation just so you get a better visualization of it- you should be pleating the folded cloth, not the pattern.  Pin each of the pleats; if you are using a filtering agent you may want to avoid pinning through it if possible, as the pins may leave holes through which particles can pass.  When all three pleats have been pinned or basted, sew along one edge of the mask, pivoting at the bottom, continue across the bottom, then up the opposite side.
The first fold in the fabric is done on fold line A
Bring Fold line A to Placement line A on the fabric
Fold and pin all three pleats

If you are using elastic, cut two pieces 7” long (cut them shorter for people with small heads and children) and tack them to the corners like this commercially-available surgical mask.

Otherwise tack one end of each of your 15 long head ties to the corners.

Completed mask

Always wash your hands before putting on and removing your mask, and avoid touching the mask itself while removing it- only use the straps. Wash your mask after every use, and avoid touching your face. Wishing everyone stays healthy and that we come out of this crisis soon.

Happy Quarantine! ?

  1. Hello – I have most of the supplies needed (just need to buy wire) and can make masks from home – how do I know where the drop off centers are in Rochester, NY? I could not locate them on this site.
    Are these masks washable with the wire in them? I have been washing the masks I’ve made (without wire) in dye-free, perfume-free detergent and letting them air dry before donating them. When I give them away, I have been including instructions for washing them so they can be kept clean and re-used.

    Thank you for organizing this effort –
    Amy Moyer

    1. Amy, that’s excellent! We suggest using an aluminum wire because it doesn’t rust and molds easily – some people have even had success using twist-ties. For the vast majority of us, mild detergent will work to clean the masks and they should be cleaned daily when worn. Could you email me a copy of the instructions you’ve been providing, please?

      The drop-off locations are being finalized now and will be posted in an Opportunity page where volunteers can commit a certain number of masks until that group’s needs are met.

      Happy to help!

    2. Good morning – here’s the washing instructions that I have been sharing –
      Face Mask – Washing Instructions
      • Wash mask in warm water, low spin cycle
      • Let air dry

  2. By the way, thank you for the pattern and instructions. I was able to print the pattern out on two pages by using the Microsoft clipping tool to save each half of the pattern and printing that. The pattern, as it was printed was only 7.5″ wide and when combined 14″ long. I trimmed the pattern only on one of the long sides so that the extra printer paper made the pattern the prescribed 8″ wide.

    1. I’m sorry you had to go through those extra, unintended steps. But I’m flattered and honored you are so excited to jump right in! We’re all learning as we go and adapting as fast as we can. Taking your advice, we’ve edited the base pattern and made it two pages and 14″x7.5″ in Version 3.

  3. Thank you so much for these instructions. I’m having a little trouble printing the pattern to size, so am creating a 14-3/4″ x 8″ pattern that I can use. Can you provide the exact measurements between the pleats and the folds? Thanks again!

    1. Thanks for your enthusiasm! We’ve posted Version 3 of the pattern that might be easier to print and use.

      The pleats are a “knife pleat” and starting at Fold line A fold an inch of the material in half and under itself to Placement line A. Go up half an inch to Fold line B and repeat so on and so forth. We’re preparing a video now and will post as soon as it’s edited. Hope that helps!
