Strange times call for strange sewing!
Tim had a neck warmer made by a local company that we often use when snowboarding, hiking or snowshoeing. It's just a triangle made from flannel, lined with polar fleece, fastened with velcro at the back of the neck.
It's great for neck-warming, but less great for wearing as a mask when you encounter other folks on the trail, the lift or about town... not enough room or shaping for the nose!
I took the neck-warmer and decided to smash it together with a mask pattern I've been using that has a dart at the nose, adding the nose shaping to the top of the triangle.
I also lengthened the ends of the triangle to give a bit more room for the nose and the head when the mask/warmer is pulled up.
I included a piece of wire at the nose bridge, inside the seam allowance, for extra protection from glasses/goggle fogging.
My brother's is two layers of the perfect UPS-brown flannel from Joann. He's a UPS driver and I thought the mask/neck warmer combo would be well suited to cold days in the truck.
