Here's what you need:
Approximately 4 ounces of melt and pour soap base
Mini bath puff (I got mine from Parasox on etsy)
Fragrance oil (I used Cherry Blossom from Sahara's Supplies)
Blueberry seeds for exfoliation (also from Sahara)
Bath bomb mold (from...you guessed it!...Sahara)
A spoon for mixing
Knife for cutting
Measuring glass to melt your soap in
Have all your supplies? Okay, let's get started! First you need to cut up your soap base and measure out 2 ounces. Melt it in the microwave (about 20 seconds should do the trick), add about 1/4 tsp fragrance oil, a bit of blueberry seeds, and mix it all together.
Now, set your mini puff in one half of the bath bomb mold. I recommend greasing the mold a bit so your soap doesn't stick.
Carefully pour your soap mixture into the mold. You'll need to pull the puff away from the sides a bit to get it in there. Pour slowly so the puff has time to absorb some of the soap. Now, go grab a cup of coffee and wait for this to dry.
Is it dry? Alright, next step!
Unmold the dry soap that you made earlier. I tried doing this with the first half still in the mold but the mold won't close completely and you'll have a little gap between the two halves. Very carefully and very slowly set it into the melted soap, puff side down. You'll want to put something under it to catch the soap that runs out over the side. Trust me, now matter how slow you go it's going to happen.
We're done! Well, almost. Go grab a book or watch tv for about 3o minutes and then come back and unmold your creation!
P.S. I don't recommend making your soap outside like I did. I only did this for the purpose of taking pictures in the natural lighting.
