I soap in the garage, which is downstairs. Here's what I do: 1. I mix my lye first and let it sit for quite awhile. 2. Then I measure out my hard oils and take them upstairs to microwave. I let them sit for quite awhile as well. 3. I carry the cooled hard oils back down to the garage. I measure out my soft oils and mix with the hard oils. 4. I mix together my eo blend (if that is what I am using). 5. If I'm using colorant or additives, I get that measured out. I mix colorant or clays with a bit of the soaping oil until completely dissolved (I hate spots in my soap, lol) 6. I put away the scale, gloves, goggles, etc. and get everything in place for the soaping (mold, stick blender, paper towels, etc). I don't have to line my mold 'cause it's an Upland. 7. Then I pour the lye water into the oils, add any additives or color, etc. Walaa! Soap!
