Ah, the wonderful world of melt-and-pour soap making! For those of you who thrive on instant gratification, there's no better outlet for your creativity than customizing your own soap. Here's a little project that you really can't mess up. Start with a pre-made soap base, melt it in the microwave, add color and fragrance and pour a thin layer into our
flexible brownie pan tray. Let that layer harden, remove it from the mold (this is where the flexible mold is most helpful), and repeat with any color or combination of colors you desire. Keep in mind that your fragrance should be consistent with each layer because they will be mixed together in the embedding process.
After you've made a few different hardened layers, cut them up in squares and rectangles. Melt down some more soap and leave it clear or lightly tinted so you can see the layers. This freshly melted soap is going to work as the glue to hold your chopped pieces together. Fragrance is optional. Using the same tray mold, pour a thin layer of fresh soap and spray with rubbing alcohol. Don't forget to generously spray the cut pieces with rubbing alcohol, too, before embedding them into the melted soap. Now, place your squares and rectangles into the wet layer, and alternate between pouring melted soap and embedding the cut pieces.
Keep adding until you fill the mold, spray the top one last time to get rid of those pesky bubbles, and let it harden. Release the soap from the mold and cut into bars with a kitchen knife,
cutter/scraper, or
crinkle cutter. There you go! A beautiful, vibrant and original work of art, er... soap. Give it a try!
This bright, fun soap is built up in layers and embeds. There is no end of color combos, shapes and design possibilities with this project, so go for it and have fun! 
To make this soap, start with a yellow layer on the bottom of your loaf mold. I used yellow mica in a clear base for the most vibrant color. Let it harden, spray really well with rubbing alcohol and pour a thin layer of opaque base on top and let that harden.
I went ahead and made some basic shaped layered bars for some color, then cut them in pieces to embed. Line them up however you like in the mold, but keep in mind you are cutting cross sections. Spray rubbing alcohol on everything! The embeds and the hardened soap in the mold need to be sprayed so they all stick together. 
I finished up by double-pouring the rest of my opaque base on the top, split into two colors. Double-pouring is just pouring two colors side by side at the same time. It helps to have fairly cool soap at this stage so they don't bleed into each other too much. Spray the surface and let it harden. Then the fun part: cutting into bars and revealing your soapy masterpiece!
