This is the video from the hospital in Iowa where the previous instructions were from, I think. A bit of additional info, but not needed to sew mask.

***Neither mention how to sew in a flexible wire (unless I missed it) that you should do if you are making for yourself and family ect. Also I would stitch all around the finished edges to keep fabric layers together more.

You can add additional disposalable filter to mask, what ever that may be.

Xxl size. I haven't done it yet for this mask but will. I have a BIL that has an exceptionally large head. I will just add an inch all around the pattern. I did that for the pleated masks and work well for him.

This one has different sizes on the pattern template for fitted mask, downloadable for toddler to adult.

They do ask for your email however before you can download. I did it, seems fine.

Face Mask This one looks really good

Joann, that looks like a good pattern. I like how she did the adjustable elastic with the beads or washers I will definitely use that idea. I've been using strips of knit fabric for ties since I have no elastic left in my old stash of sewing stuff. It's difficult to tie them for a good fit. I've been leaving mine untied that I have given to people so they could tie themselves for a good fit.

I've been using bed sheets that I have hoarded to make rag rugs that I've not used up yet. Only use the cotton or blend that are nice and thick, not the thinner ones.

My wife's current mirror ornament.

Izzy, that's the pattern that I've been using. Thanks for the tip about sewing in the flexible wire (I use pipe cleaners) for family use. I have not done that yet, but it will be easy to do. I think they should still be washable, and that was my only concern.

I absolutely love the pattern by the nurse that I posted. It fits well, easy to use and no elastic needed. Takes very little time to make.

***just a note

The pattern listed on the first post has instructions with measurements for you to make pattern if you don't have a printer.

I do use pipe cleaners for nose wire. I've heard they can rust, but I don't know for sure. I just found a spool with more than I could need of suitable thinner aluminum wire at my mom's I am going to try.

I have been using the coated floral wire I have a whole spool. I fold over the ends a couple of times and use plyers to smash it flat.

I have made Hundred's of isolation mask's. Free to all. Nothing fancy and very basic, not a need for filters unless you are in the direct line of the Virus. No need for Wire or anything else.

Yesterday I top stitched the masks I had made, but first I sewed the pipe cleaners into the seam allowance at the top of the mask using a zigzag stitch, and that worked very well. Now the masks fit very snugly at the top, so that air does not blow up into one's eyes or fog one's glasses.

I don't know about pipe cleaners rusting, but I have been using them for cleaning parts of hummingbird feeders and have not noticed any rust. I generally use them twice, and so they sit around for a bit while still wet.

I use shop rags for the inner filter, which is probably not necessary, but it doesn't hurt.

Fyi: I've been testing the pipe cleaners for the past two days wrapped up in a wet paper towel. No sign of rust. But may not be true for all pipe cleaners. They probably all made with a different metal wire.
