From what I have gathered, blending is making your own tobacco from scratch and mixing is when you use several blends that you have purchased. Anyways I have mixed (a very small amount) 1/4 of each: Frog Morton, Plum Cake, Squadron Leader, and Christmass Cookie in the hopes of creating the perfect English. Half of me thinks this is going to be really good and the other half is screaming "YOU JUST PUT A GOOD AROMATIC IN WITH GOOD ENGLISH YOU MORON, NOW THEY ARE BOTH RUINED!" So I'll let it maranade for a day or two and give it a try lol, there seems to be enough for 3 medium bowls. The aromatic was mostly to bring down the nicotine content a notch.
