I'm in agreement with Carebear about not doing the additives especially if this is your first batch. I probably wouldn't even do HP and just do CP and do it with a whisk instead of a stickblender. If you're not happy with the results and you've done something more complicated, it's going to be harder to figure out what went wrong. I'm getting the idea that it's very important to you to understand the "why's" of soapmaking which is good. For that reason I would do the basic soap, watch what happens as it changes, keep notes on what oils you used and the results, and then make changes and start doing additives from there. Just my opinion, and I'm new at this myself.:rolleyes2
