Yeah, don't burn it up

There's really no way you can mess up iron on veneer. Just heat it up again and the glue softens. Either reposition or peel it off and start over.
Assuming I don't screw it up, I'll have over half the cloth left. Reece has already staked a claim on it.
Not sure what you have it mind. I've left a trail of partially finished projects behind me that I really need to finish off
