I don't think there is a single soap maker that hasn’t tried to run before they learned to crawl. And that includes the folks who carefully researched for months, or year or so before they took spatula in hand.
I started with Olive, Coconut, Palm and Castor Oils; makes a very nice soap. But I wanted to make a “special” soap, I wanted to be different (doesn’t everyone?) and so I bought Cherry Kernel Oil, Sweet Almond Oil, Macadamia Nut Oil, Avocado Oil, Cocoa Butter, Shea Butter, Mango Butter and I really wanted some Cranberry Butter, but OMG its expensive. One soap I made had nine different oils/butters it in...never again.
Can we talk about molds? I started with 10” Silicone Mold (2 lbs). Then I bought a second one, and two 1 lb molds. The latter was because I had screwed up several batches and disliked wasting so much money. Then came the two 4-cavity Round molds for Salt Soaps, followed by the three 15-cavity Round molds for sample soaps. Then there was the two 6-cavity molds I bought on clearance for kid size/travel-size soaps along with another 2 lb mold, this one was a wood mold with silicone insert and sliding bottom. Oh...cant forget the 2 lb mold I got from Hobby Lobby that I’ve only used twice. And the cute mold that I picked up on clearance for guest soaps. Then there are the two flower molds that I want to paint. And the four 6-cavity Bee molds for Lotion Bars. And the two 4 lb new-to-me RED molds and baskets I bought from another soaper.
Colorants I haven’t done too bad with...so okay I have three foot shelf double-stacked, but that’s only because a quarter of it has fragrance oils on it. Which is where I have really gotten into trouble and why I am in time out when it comes to buying scents. When I did and inventory last month, I discovered I was kind of out-of-control...I had just over 70 bottles and some were duplicates, triplicates and I even had four of one scent. In my defense, the majority of my fragrance oils are 2 oz bottles; hard lesson learned, I only buy sample quantities of scents until I try them.
I am happy to say that I haven’t gone crazy with the “additives”. I do add Kaolin Clay and Sodium Lactate to my soaps and Arrowroot Powder to my Lotion bars, but that's it.

No curing soaps long enough.
Not understanding that HP soap has to cure as long a CP soap.
Making illegal (in the US) 'cosmetic' and 'drug' claims.
Thinking you're going to get rich making soap.
