Liz, that's exactly what I was thinking when I was writing my first reply, it's like my kindergarden pictures but now I know to use MUCH less water!
@Julia, I also use Vodka with my luster dust etc. ~ I learned the hard way when I first started and the luster dust didn't have instructions ... so from experience (and a ruined beautiful set of cookies) NEVER USE WATER WITH LUSTER DUST! What a memory that is! ;-)
