I am sure you did, but make sure to cut the soap up in little pieces before microwaving it. On a cookie sheet? I would give it a try, but watch the soap because MP gets very hard-and you may find it's hard to cut with a cookie cutter. Best of luck!
And oh- about buying FO. That's a good question. It is trial & error. So many people have different recipes, etc...it's personal taste. I would first look for somewhere that has good shipping rates to your location. You'll soon find out shipping take a HUGE chunk out of profit, etc...
