Ooooh I have had this happen. Your FO was waaaaay to thick. When you poured it into the blue wax, the amber tint from the fo made it look green. Your FO never incorporated. Hate to tell ya, but your gonna need to try again with a better FO. The FO should have a smooth light consistency and a light color. Anything darker than a yellow color I have never had good results with. They always sink. Impossible to incorporate. You can heat the FO a bit in warm water, but that has never worked for me. You can stir til your arm falls off, again, never worked for me. Good Luck! Get yourself a prepaid Visa from Wallyworld. OR you can get paypal, most suppliers take that too.
