Whoops sorry attached the wrong quote - I meant to attach the original one from Mrs.dr.ronI imagine they would be very comfortable to wear.
Love your fabrics.
I have just spent some time making masks too. So much for my proper work. It seemed like a good idea to sort out a good pattern and fit. I am in WA so not currently needed but it doubless will be sometime soon. I wanted to have some ready for family who don't sew.
I have a load of fabric of all sorts so have started out with all the suitable cotton and poly cotton scraps to see how they go. Made 8 so far plus a couple of not so good fits getting it right. The shape is similar to yours which seems a comfortable shape to wear.
I am using the info from the Victorian health website about fabric so 3 layer and the middle one is from the 'green' bag type fabric. I find that is quite good as it also holds it away from the nose nicely. I have sewn in a stainless steel wire for the nose fit. Tried a few different bits but couldn't get a nice tight fit. I have tested with my glasses on and I can get it so they don't fog up.
Its kind of fun!
