$70 Tip...For Free!

I signed up for a beginning acrylics class this spring, thinking that I might be missing something since I never had painting lessons.  Well, it was a little more basic than I thought, but I did come away with one helpful tip for my $70, and I'll share it with you for free!  Acrylic paint tends to be translucent, so if you're painting a flower it can get frustrating adding layer after layer of paint right out of the tube, and it still dries too see-through.  Here's the tip: white paint is opaque.  Always add a tiny bit of white to any color you need to be opaque, and viola!  No more see-through flower petals!  There, I just saved you $70!
