Depending whether you blob it, dab it, pull it, or brush it, different effects can be achieved, and mixing colours is fun too. I like these butterflies (using die-cut board).
One thing to remember, it takes an age to dry. Did all this with a friend, and had to transport home - put them into a box lid, in the boot of my car. By the time I got home, they had slipped into each other, and stuck together - oh well - lesson learned!
