Simpler boat style - an attempt at a no nose-wire 3D mask

Iris Luckhaus has an attractive mask that has a wee pinch for the nose shape that looks quire snug by default (no nose wire). I thought I'd attempt something similar.

Same template as for the previous boat style I made, but no twists at the sides, and no nose wire sewn in.  Three layers of 80gsm SBPP (no cotton or anything else):

The two parallel horizontal lines are 6.5 cm apart.

Fits a nose quite well, but it itsn't perfectly tight.

This would be 75% PFE by the recent lab tests, but without the 

nose wire making things perfectly snug, maybe 5% less.  MORE TESTS RESULTS HERE - TODO

Of course you could use the aluminum strips to make that happen. Either glued on top, or sewn in:

Very quick to make - maybe 8 mins solo, or 6 mins with someone 

helping making batches of them at a time.
