Here is the supplier where I get the blanket pins I mentioned on the October 26, 2022 NNPG Amateur Radio Prepper's Net:
Survival Resources > Misc. Items > 3" Blanket PinI get quite a few different items from Survival Resources including the Aqua Pouch and Aqua Pouch Plus; the tubular flasks (soda bottle blanks); various other containers; Space Saver Cup; Pathfinder 25oz cup, lid, and nesting stove; various fire-related items; several first-aid items; several different compasses; some books; and other stuff.
Just my opinion.
