Tweaking no nose wire boat-style designs

 Reminder of a boat mask with twists as it was sewn and copper mains flex nose wire inside the fabric - that fits very well.

And a simpler boat style with aluminum nose wire on the outside. I've work this to the 

supermarket a few times. This fits well with the wire, but without it has small gaps.  

That aluminum nose wire is not going to survive beyond a week of use, sadly:

---

This one was an attempt to make some additional sewn lines to 

force a better nose fit without wire. The mask was also folded inside 

out as an experiment.  It didn't really work

We should always remember that we should not run two 

experiments at the same time, if results are important!

Another attempt to sew the nose area "up and out". 

This still had gaps around the nose - another reject:

Closer, i think. A different line sewn to force a tighter nose shape:

The last of those three has nylon zip ties pushed into the pocket just made. 

It is forcing a bow rather than a sharp right angle, which is more attractive 

and increases the surface area of he breathable fabric a little.

Unpicking one of those, and having another go at the V:

This fits quite well - nice and tight around the nose without pinching it.
