Where to purchase Kydex and holser making supplies?

Since I have been bored sitting in my house, I have been looking at making my own OWB holster for my G17 and an older FNP9 (barely any holsters out there for that one), and was thinking about trying my hand at making my own kydex holsters.I have been looking at a couple of places and while I'm sure they are OK, some of them look sketchyhttps://https://ift.tt/2KkxdDW https://ift.tt/2CQ1oNg https://ift.tt/2wkDZ70 https://ift.tt/1PNB7i7 https://ift.tt/2wWYh9j looking for reccommendations for places to purchase a kit or at least the supplies to make a few holsters on my own. via /r/CCW https://ift.tt/3anZbtb
