Krisb, I second that:
Covid-19 phrase for today: Elastic is the new toilet paper.
This morning I have been to my usual haberdashery supplier. This happens to be a wholesale store and they were sold out of elastic and almost sold out of bands that could work as straps. I managed to get enough for 25 masks though. I have places an order for the elastic. I was wondering if other parts of the world have the problem, too, and apparently so :/
