I just finished making my own neck seal. The one on the vest that my mother made was too thin and would fall down once I started heating up. I don't have any pictures to post, but it's really simple, and you don't have to sew. I used some left over fabric from the vest we made (a light grey 100% cotton)and cut out a strip 6" x 20", this will be the base. Using Goop glue, I folded over and glued the top and bottom edges so the height is now 5". Then I cut out 6 pieces of the same fabric 7" x 22". Starting at the bottom edge I rolled them up and glued the outside edge down, so I now had six 20" fabric tubes. Then I glued each of those onto the base with all of the excess on one side. The excess 2" is folded over and glued onto the back (this will be the edge that shows). Use an epoxy glue to set your velcro, and your good to go. It looks awesome, took less than an hour, and I had all the materials already.
