Oh ok! Thank you for your help!

Is it ok to mix different types of foundation together? For example, I have a few scoops of Heavy Coverage foundation left and a few scoops of Medium Coverage left. Is it ok to mix them together?

First I'd like to say that I just tried SN and I love it! The only problem is, it seems to aggravate my asthma. I have tried mineral makeup several times before and it seems to happen every time. I tried not to breathe it in but maybe I'm doing something wrong? Does anyone else have this experience?...
