I had so much fun making these! I hesitate to call them "home-made" soaps because technically, I didn't MAKE the soap... I just melted down glycerine, added scent and a cute little fishy, and put it in a form. But I am pretty sure that for all intents and purposes- this is a little tutorial on "making" soap.
I got the idea while searching for "Ocean Themed Baby Shower Favors" on Pinterest. All of the examples I saw were poured directly into the cellophane bag- but I preferred to use a mold for a more appealing shape of soap.
I purchased a giant block of Glycerine at Michael's. I suggest using a coupon for this item- it can get a little pricey. I softened the giant block with a bit of hot water on the bottom of the bucket to loosen it and remove it from the pail.
Start cutting off small chunks and melt in a microwave safe bowl. Instructions said to melt for 30 seconds at first, then at 10 second increments until it is melted. You only need it just hot enough to melt.
Once the glycerine is melted, stir in a few drops of essential oil or scent if you desire. I used a tropical one for most of my soaps. Then fill each mold about ¾ full.
Immediately spray the surface with rubbing alcohol to make any bubbles that have formed disappear. Next drop in your little fishy. I found mine at a toy store- but if you allow enough time for shipping I suggest ordering online- they are MUCH cheaper! You can spray the alcohol again for bubbles if you like, but I noticed my fishy's moved if I did that so I suggest doing it first.
Next, place your fishy's on a tray and put them in the freezer for about 10-15 minutes. Once they set, melt more glycerine, add more scent and fill the remaining ¼ of each mold.
Put them back in the freezer for another 10-15 minutes until they set. They should easily pop out of the molds, but if they don't you can set the molds in a cookie sheet filled with hot water for a few seconds just to loosen them.
I picked up a fish bowl to put them in, and had them by the front door so everyone knew to take one home. This was a really fun little project and I will definitely be making some soap again!
