Discovering a new craft is always my favorite part about sourcing for Remnants. Soap making isn't exactly a new craft, but new to me.
Fabric, I understood. Books, I figured out fairly quickly. But soap molds were strange, unfamiliar objects. Tools, but also more personal than most tools, because whoever used them last was pouring something they'd mixed by hand, scented and colored to their own taste, into a shape they'd chosen on purpose. By the time a mold gets to me, it's carried dozens, maybe hundreds, of small decisions someone else made.
The tool that made me pay attention
When I started really looking closely at soap-making instead of just listing pieces: the Cheshire Cat Soap Mold Angler is what did it.
I'll clarify what it actually is first, because the name trips people up, myself included at first. It's not a mold. It's a stand, shaped like a grinning cat, that holds a standard loaf mold tilted up at an angle while you pour. That tilt is the whole point. When soap batter goes into a mold that's sitting at an angle instead of flat, each layer settles diagonally instead of stacking straight across, which is how soap makers get those clean angled layers and ombré effects without any extra tools or guesswork.
It's a genuinely well-made piece, too, beyond just being clever. Good detail in the grin, clean lines around the ears and tail, and sturdy enough to actually hold a full loaf mold of wet soap batter without wobbling, which matters more than it sounds like it would. A wobble at the wrong moment ruins a pour you can't redo. The angler made me see how much goes into soap making that I hadn't ever considered before.
Why buying used actually matters here
Silicone soap molds are one of those categories where "buy new" feels like the default, but it really shouldn't be.
New silicone production has a real footprint, and a lot of soap-mold designs, seasonal shapes especially, get produced for a single season and then discontinued. That Designed with a Twist - Christmas Themed Silicone Soap-Making Molds Set, a Boho 3D Cherries Bath Bomb Mold, or a specific run like the Crafter's Choice Round Ball 2/14in Mold #1801 might not be back in production next year in that exact design. Buying it secondhand isn't a compromise, it's often the only way to get that specific shape at all.
There's also just the plain economics of it. A mold that costs fifteen or twenty dollars new might come through Remnants for a third of that, in perfectly good working condition, because the person who owned it moved on to a different hobby, or scaled down their soap making, or simply had more molds than they could use. Soap makers tend to accumulate molds the way quilters accumulate fabric. That's good news for anyone just getting started who doesn't want to spend a lot to find out if they even like the hobby.
The most important rule when buying used
One thing I learned: once a mold has been used for soap, don't use it for food again.
This isn't about hygiene in the way you'd think. Soap and food-safe silicone can start out as the exact same material. The problem is fragrance oil. It's designed to cling. Silicone is porous at a microscopic level, and fragrance oils, especially the stronger ones used in cold process and melt-and-pour soap, work their way into that surface and don't fully let go, even after careful washing. You can scrub a soap mold until it looks spotless and still end up with a faint perfume baked into your next batch of muffins.
So the molds I list for soap making, I list only for soap making. If a mold has clearly lived a food life before this one, I'll say so and treat it differently. But once something crosses over into soap, in my shop, it stays there. It's a small rule, but it's one I don't bend.
Who to follow if you're just starting out
I get asked this a lot, so here's where I'd point a total beginner.
Royalty Soaps is probably the most approachable entry point into cold process soap making on YouTube right now. The videos are relaxed, genuinely educational, and don't assume prior knowledge, which matters a lot when terms like "trace" and "gel phase" are still new to you.
Bramble Berry's Soap Queen channel and blog are worth bookmarking specifically for technique breakdowns. It's less personality-driven and more reference-style, which is useful once you've watched a few full soap-making videos and want to go back and actually understand why a step works the way it does.
Elly's Everyday Soap Making is a good one for melt-and-pour specifically, if you want to start there before working up to cold process. The pacing is patient, and there's a real emphasis on troubleshooting when something doesn't turn out right, which is honestly the content beginners need most and get the least of.
None of these are affiliated with Remnants, I just genuinely think they're where I'd send someone starting from zero.
Soap and bath supplies have become one of my favorite categories to source for, mostly because the tools carry so much evidence of use. A mold with the corners slightly softened tells you someone poured dozens of batches through it. A cutter with a worn handle tells you someone found a rhythm they liked. None of that shows up in a listing photo the way it shows up when the item is actually in your hands.
The full soap making collection is where I keep everything as it comes in, if you want to see what's currently available.
