Five iterations to my modifications to Ragmask

1. top left  - as RagMask 2.2 with medium weight satin as the filter, sandwhiched between two laters of 400-thread cotton.
2. center left  - as #1 but with one layer of 400-thread cotton (four straps - two ties together with elastic)
3. top right - as #2 but with two straps only made from the same 400-thread cotton
4. center right - as #3 but two layers of thinner satin (from sheets), and a simpler retainer.
5. bottom - as #4 but four layers of thinner satin (from sheets)

So I have worn #3 and #4 out on shopping trips and they didn't slip down, but I was careful with how much I moved my head while wearing it.
