Fog-Free Face Mask

This is a face mask designed to be worn by people that have an issue with their breath fogging up their glasses while using a cloth face mask! Please note the following disclaimer:

Supplies

T-shirt

Scissors (Fabric scissors work best but any sharp pair will work well)

(Marker optional)

Step 1: Grab Materials

The first step is to lay out your t-shirt that's going to be cut into a face mask. The red lines on the picture show where the t-shirt needs to be cut to divide it into four semi-equal sections. In words, the sleeves are being cut off, and the shirt is being cut up the sides, the front, and back.

Step 2: Finished T-shirt Section

This is what one of your cut t-shirt sections should look like.

Step 3: Cut Off the Neckline

To make things easier, simply cut off the neck line of the t-shirt section by cutting straight across horizontally. The picture shows the t-shirt section after the neckline is removed.

Step 4: Study the Drawing

The drawing shows the main dimensions of the face mask in mm. The dimensions do not need to be exactly spot on. I recommend marking the main trapezoid shape onto a piece of paper and cutting it out to use as a template for the next step.

Step 5: Attach Template and Mark Features

Attach the template to the t-shirt section and trace on any other features from the drawing you want to be cut accurately during construction.

Step 6: Cut It All Out

Simply cut out the trace lines and template and you'll have close to the finished product. Once you have the shape cut out, make sure to cut next to the mounting strips at the top of the mask to free them from the foldable fabric section.

Step 7: Fold the Fabric and Cut Holes

Now you can cut a little slit in a top mounting strip by folding the strip over itself and snipping a little line to create a slit. Do this for both mounting strips. This is where the mask attaches to the glasses.

The large fabric rectangle at the top folds into the inside of the mask to act as a top seal when the mask is applied. I recommend folding the fabric over itself twice to ensure the most comfortable and effective fit for eliminating foggy glasses.

Step 8: Try It on and Adjust If Necessary

Go ahead and try it on! The glasses slide through the slits of the top mounting straps and the bottom straps tie around the back of your neck.

You might find that the dimensions listed are not the right fit and that's alright! You should have three other unused t-shirt sections that you can use to try again with smaller or larger dimensions! The mask should sit flush along the side of your face. The top seal should make the bottom of the mask the exit with the least resistance to exhaust air, eliminating any issue of foggy glasses.

Thanks for reading!

Happy building!
