Where do y'all buy grafting pins? I've tried searching online, but I'm not able to find any suppliers. Most grafting supplies I find are knives, tape, etc. for grafting fruit trees and whatnot.
The grafting pins actually suck imo. They are meant to hold down tatami mats. The holding force relies on friction of the green plastic against the metal, and it does not hold very firmly. A strong scion could push it out. I just use regular thumbtacks now
