i just used a small pvc pipe and made the white with a tiny tiny bit of peach color. i made the soap and let it set up for 2 days, then i made some black soap and poured in a small amount into my log mold. i added the moon to the soap and then continued pouring the black soap until i was out. made the top of the black textured so that i could make "hills" out of the dark green. i left the top of the soap as flat as possible. when i unmolded, i turned the soap upside down so that the grass is on the bottom.
