I picked up some Van Der Hagen soap today to add some old spice to. I melted it down using the double-boiler method, added the OS, and right before I took it off the heat, noticed a pump bottle of Curel moisturizer on the counter. It's unscented and full of glycerin so I squirted a couple pumps into the soap mixture. My hope is that the glycerin will help produce a nicer lather and might add a bit of moisturizing too. I did a quick search and it doesn't look like anyone has tried this yet so I'll let you know how it turns out.
