Melt and pour are quick to pop'em out of the mold and getting them on the shelf ready to self. Is a bit easier. But for me is a bit more expensive than just getting the ingredients to make a soap from scratch like Cold Process and Hot Process Soaps. In addition to it in M&P you do not have control of what the actual ingredients are in a soap base, I had no clue what were in mind since the people who sold me the base did not bother in telling me what were the ingredients or at least provide me some hints on them. Sure you have a free range of possibilities in making wonderful colorful soaps e.g with neon bright colors, fun shape soaps with interesting colors that get anyones attention even fool people into thinking they are food if you use a food like mold e.g cup cake molds. You have more space for your imagination when it comes to shape, color and you get an actual idea of what the final product can be before you popped out of the mold. Unlike CP you are always in awe with every batch that you make, also one little misstep can alter the end results. I am a newbie with CP and I am loving more than M&P.
CP is therapeutic, also me being a control freak in what actual goes into the things I make is perfect. Is cheaper depending what kinds of oils you are using and most of the ingredients are available in your kitchen pantry if you look closely. I am liking doing the CP soaps. But I am tired of hearing some people telling me that they do not understand why CP is an artisan soap since they do not have those extravagant fool me shapes,I tell them well contrary to M&P I can but if I make them with a ctually tell you what are the ingridients of the soap and you would not feel sorry to use them. Instead you will feel

when you know that the ingridients in your kitchen are the ones that help in making that soap you are using.
Both for me are artisans, now it depends who is your market, how fast you want them to be, the time that you have to make them, and what gets your attention.
