Start with two simple units - a split square and a half-square triangle.
Combine them to make a simple block.
Now comes the fun. Play with the block. Color it different ways. Combine it in a variety of settings
Every block has potential. To find that potential you need to play with it. Sometimes you find something you like right away. Sometimes you have to play for a while. Sometimes you have to put it aside and try again another day. But if you keep trying you will eventually find something you like.
