I’m not going to pretend I’m a professional at this… sewing is an old-old hobby. I’m self taught, and sort of just make things up a long the way. (However, I did just watch this video with an expert who was doing all the things I thought I did because I was lazy! Validation! LOL!)
Anyway, I thought it might be nice to have some instructions to go along with the pattern, so you could see step by step how I’m putting them together. These instructions are sewing one mask, but I will note that I made these in sets of 12 and batch everything together.
Why did I Make this Pattern?
Yes, I know there are three main patterns out there that everyone else is using (circle, mad-max version, and pleated). When I decided I wanted to do this, I read everything I could to learn the space, to learn the need, and what was out there. What did I find out? There’s no standard. Not for making them, and not for the need. Everyone wants different things. So I felt like that left space to add a design that attempted to solve a few of the problems I was seeing expressed. So what am I hoping to address?
Breathability
This design is 2 layers. That’s the number recommended in that most reference article about preferred materials. They found the trade off for slightly increased filtering wasn’t balanced with the reduction in air. And, I people I knew directly in the medical field relayed information that some of the ones coming in were too thick. In examples online, I saw that the filter pockets were being added with extra layers. Side note: As this week has gone on, a version of the pleated one with a slit for a pocket has become more popular.
Fit & Seal
Another complain I saw was masks not fitting tight around the nose and chin. The flaps on these flip up in a way that forms snug around the wearers face.
Multi-functional
Some of the common patterns work well as covers for real medical masks. This seems to be the most common use case right now to extend the life of the existing supplies; however those are for staff. I thought they looked a little large in the event of a last resort emergency and the wearer needed the fabric one on it’s own, or if the fabric mask was being given to a patient to prevent spread. This flat-fold pattern fits well on it’s own, as well as, over an N95 mask.
How did I make the pattern?
One women referenced a real N95 mask her husband had from work that had flip up flaps and sealed well. I modeled this design off that photo of the 3M Aura mask. I don’t have one in person, so I had to look up dimensions and then guess for the rest. I built paper prototypes first. Then drew the design in Illustrator, printed it, and tested it out. Making adjustments on sizing until I felt it was pretty good.
Materials
- 1 yard fabric for flaps
- 1 yard fabric for front
- 80 inches of 1/2″ double fold bias tape (or make your own with 2″ strips)
- Thread. I used a medium duty since I know they will be washed heavily.
The article that most reference explains that it’s best if it’s a weave and not a knit so that there is no stretch, and that because of risk vs reward of capture & breathability, 100% cotton t-shirt material and 100% cotton pillowcases are best. I am using 100% cotton with a tight weave, like quilting fabric.

medical disposable is going up
What do you mean? The cost of disposable face masks is increasing?
This excellent website certainly has all the information and facts I needed concerning this subject and didn’t know who to ask.
