The CDC, Washington State Department of Health and county health officials all say it is a good idea to wear a mask while in public during this COVID-19 outbreak. They also say commercially produced medical masks need to reserved for healthcare workers, first responders and others who really need them so, that means you could need to make your own mask. There are many guidelines out there including a how-to list of easy-to-make options on the CDC website.
But those aren't the only choices.
Cloth masks are highly recommended but another material that could be an effective mask fabric, isn't normally considered a fabric at all. It's the blue shop towels in your garage. Multiple sources including one of the scientists who helped develop the N95 Mask, quoted in the Washington Post, say the blue paper-towel-like shop rags could be an excellent filter.
In the video above I show you how to make a variation of a popular no-sew blue shop towel mask and a fitted multilayer cloth mask with a shop towel insert. I'm not an expert, just a do-it-yourselfer showing you what I've made for me and my family. Use at your own risk.
