The change in message is weird. We have signs at work that say don't wear one unless you're sick － They literally lied to us about the effectiveness of masks in order to manipulate us into not buying them. They're not 100% effective but do prevent at least half of virus cells from crossing the fabric. I'm gonna try to make some today. － They had to make sure they had shook down everyone who was willing to give up their supply first I have a sewing machine and some extra fabric, do you have a pattern you're using? － I'm gonna try this one but there's a few out there. I don't learn well from videos but there's a bunch of them if you search. － https://www.craftpassion.com/face-mask-sewing-pattern/ So if I've been in stores in the past week around people and not wearing a mask, I should start now? － If you're able to make or acquire one, yes.
