need~ muffin tin (if you use that it is better to rub some coconut oil on it so they do not stick, or you could just use a non stick tray) few Shopkins clear glycerin soap essential oil (we used lavender) Start by melting the clear glycerin soap in a microwavable bowl for 30 seconds or until melted. Then pour into the molds. This part you can do two different ways. You could just fill the whole thing like I did for the Moo milk and then just place the Shopkin or you could fill half way and let it dry then place a Shopkin and then more soap. Either way you do it if you want to add essential oil make sure to add it before it dries. Once done let it sit in a freezer for at least half hour & done~
