I was excited yesterday to get my new soap molds from SaharasSupplies. I've found this Etsy seller to have the best prices on molds, with reasonable shipping prices. For some unknown reason, at every other site I've found, the price of shipping soap molds is nearly the same as the price of the mold itself.
The new molds I ordered, pictured above and to the left, create square 2 oz bars. The molds on the right create rectangular 4 oz bars, these are the ones I've been using for all the soaps I've made so far. I've got two of them and I've been cutting the bars in half to make the 2 oz mini soaps for my shop. Using these molds to make all the soaps has been a cost effective way to get the most bang for my buck, but it's also limited my production. Now that I've introduced the soaps in my shop and gotten a great reception, I felt confident enough to spend the money on more molds to streamline my production process. With my old system, I could only do two batches at a time and then for the mini soaps, I always had to take the extra step to cut the bars in half. With the new molds, I've now doubled the amount of molds and my 2 oz mini soaps will now have a more consistent and professional appearance.
When you think about expanding your business, take a look at the supplies that you already have and think about ways to get maximum usage out of them. After your product has been proven on the market, then consider investing in new materials to increase productivity.
