Thought I'd bump this old thread.
I just made my third batch of masks. The first pattern I used (first batch) didn't have a nose wire and didn't quite cover the chin... Maybe we just have long faces in our household.
2nd batch used a pattern I like better - has the nose wire, is tall enough to go from the bridge of the nose to the chin. Made a bunch for myself and the family.
I take a longish walk daily with the dog - and have decided I need to be able to toss the mask in the wash as soon as I get home. After an hour if walking it is damp and gross. So I didn't have enough masks for myself despite having made to batches.
3rd batch I modified to sew the wire in (I had it extractable until I figured out that pipe cleaners can indeed be washed. I also did two with elastic over the ears vs ties.
All have pockets for filters and are 2 layers plus filter.
I am *NOT* a seamstress.... but am happy with the results.
The tan one is the first version, made from an old pillowcase and sacrificial shoe laces for ties.
The blue and green one is batch two with braided ribbon for the ties.
The black and red one is the latest, with elastic ear loops.
