If you can make a few and find one that fits, they can be quite comfortable. DH has a big head and a big nose, we scaled up a concertina mask and now he is comfy. DD broke her cheekbone at the beginning of March and is still quite tender, a concertina mask with a nose wire suits her. DS and I prefer shaped ones.
I wear one at work, it takes 1.5 - 2 hours to become uncomfortable. So then I wash my hands, go outside take off the mask, do some breathing exercises and then put a fresh one on. It is not that much hassle. I work with shielded people.
By wearing a mask, I protect others, it would be nice if others also wore one and protected me.
It's time to encourage people to wear face masks as a precautionary measure on the grounds that we have little to lose and potentially something to gain, say experts in The BMJ today.
