Given that everyone except 2 years and below are required to wear a face mask when going out, I have been looking at buying one for the kids. Apparently, it’s much more expensive to buy for kids than for adults.
So, I started looking around for templates and measurements.
Tutorial to sew a kid’s mask.
My personal favourite is by Craft Passion. Not the easiest to sew but it does include templates with filter slots. While the homemade masks are not 100% fool proof, it is better than nothing.
