I have a question, i just purchased Ky's 3&1 and the fragrance ratio is 1%. If i make 8 oz, my calculator says 0.08. How do you weigh that amount? im guessing i need a scale that reads low. I cant figure it out in grams. I suck severely at math lol. I dont normally make bath& body products, Im just doing this for a friend whos son is autistic and hooked on one perticular scent. Any help would be awesome, thanks
