Hi everyone,  I though I would post the process I used to make my neck seal for others to use if they want to try and make their own.   Materials:   Stretch fabric - I used a tshirt type elastic material for the bib and the inside of the neck piece and a elastic stretch fabric with a shiny rubber like surface for the outside of the neck piece. Batting  Paper for making a pattern. Right angle ruler. Sewing supplies.   My neck size is 17”,
