Can I sell a flame, that I havn't forged yet, and than forge it with the tc they bought it with? How much should I charge per flame? I was thinking like 10% of the forge cost, is that too much/too little?

Also, is there any non-dead flame forging organizations?

Yes you can sell flames before you've forged them and I'm not quite sure about using their tc, but im not sure. The thing if fingerprints does this for 0% fee, so it'd be hard to get customs imo.

You can make request threads like cake and furryprints have.

There's no profit to gain here tho', seeing as furryprints is great at forging flames and he doesn't take more TC than what the forge price is.

And yes, I'm pretty sure there is a flame forging org.

What they said ^^

But even if you can forge good flames you almost never sell them for the forge prize, seeing the thread you got up in market, nobody pays over 50k for a handflame.
