Okay I am going to try my best to explain...this is still new to me also. 1. You need to enter how many pounds of oils total you are using...if your mold holds 4lbs, 2lbs 2. Then pick your types of oils that you are going to use...olive, coconut, hemp, cocoa butter.... 3. Then choose the % of each oil you are going to use in the recipe, as an example 50% olive oil, 25% coconut oil, 10% cocoa butter, 15% Hemp (I am not saying use this amount it was just an example of percentages) 4. Click on compute recipe and then scroll down it will show you how much liquid, lye, and oils to use. ** Do this between step 3 and 4 if you are adding FO If you are adding Fo there is also a spot on the left side to add the amount per pound and then if you hit compute recipe it will show you how much FO to use HTH Edited: Due to my inability to add up percentages....lol
