Knapping material, Do you find petrified wood, agate, flint, chalcedony? Options

[Epadilly]

Hey I'm new to this website. But I collect knappable lithics for my personal use. I make projectile points and eccentrics by flint snapping. I find my own but I can't find enough to sustain my addiction and I don't have the time or money to go out all day every day so I thought I'd give this a shot.

I'm asking this community for help. While you are searching for gemstones or metals and you come across knappable materials (chert, flint, jasper, agate, chalcedony, high quality quartz) I'd be willing to trade you some arrowheads, spearpoints, or a knife that I make. Or I'm willing to buy it from ya for a roller or two a pound. I prefer large pieces, and they can't be freeze cracked. If you know anyone that hunts it I'd love to learn from them or help them qui dontknow, I'm reaching out for some help here, I hope this post is ok.
