I may actually have started to try this once, but got side-tracked into something more intricate since I had purchased the tools, and never really did Integlio style carving. I think this is a better way to start with carving tools when one has little to no experience with carving. (Maybe once or twice some wood burning carvings, but not carving per se.)
So now I'm looking at various videos to see how others do it and get a better idea about how to proceed. It's looking like a soap made separately first, then put a thin layer of fresh soap on top, or even dollops of color on top of one color soap after the first one sets up, then a third soap as a final thin top layer might be the way to do. Or maybe a multicolor soap underneath might be good, too, with only the top layer being a single color. We shall see what I decide.
But I want to work on something this week. If I manage to make the soap by Saturday I will take the tools and a few bars along with on our Anniversary trip to Tennessee next week. We will be staying in a remote timeshare with sketchy or no internet access. So when we aren't out and about hiking or day-tripping to Gatlinburg or Nashville, etc. this will give me something to do while relaxing in our unit.
