FACEMASK hack - you have to try this to believe it!
The cheap, blue, flimsy surgical ones that have a super loose fit around the sides...can be altered easily for a snug fit.
1. Fold the mask in half horizontally (the long way) [so you have a long thin rectangle]
2. Tie a knot in the right earloop string where both ends attach to the mask, as close to the mask as possible
3. Do the same for the left earloop string
4. On each side, tuck in the open hole above the knot to be under the knot
5. Fit the mask over your nose and chin now and look in the mirror at the difference
This will actually work with any mask that is loose fitting around the ears.
