I've been mixing the two together for a long time. I think I saw someone else say that's what they were doing. I could be wrong and that could be part of my problems. At first when I saw that a whole capsule was too much, I was pouring a little of the ingredients of one capsule into another empty capsule. This seems easier though. Maybe someone will speak up and tell us if it is ok.
I love your art. My daughter is an artist but doesn't have much time to pursue it. I would be a would-be artist except that I have no talent. haha. What does that mean? I love art quilts and would love to make some but if I ever have the time and health, I could copy ideas of the talented artists. Works for me.
