One of my students asked me to cut her out a black butterfly the other day. I guess I was really impressed because I went and made a second one today out of watercolor. This project is great for examining symmetry. You can also get some interesting details you may or not be able to predict.
Here's what you need to do. Find a shape that you like with symmetry. It can be a moose head, caribou or even a car; whatever you're into. If you have a larger project you're working on, you can incorporate inkblots too. They could make a great card, or if produced in the hundreds something greater like filling the boughs of a tree (see my 3-D section for my trees).
You'll need some kind of pigment with a glue mixed in. I used watercolor. Pipe one half of the symmetry (if you're going radial with your symmetry you have a little more work ahead of you) on one side of a ray. I used watercolor paper for this for its absorbent qualities. Fold the design in half, being sure to press down the pigment onto the other side. The harder you push the more distorted your design is going to become. The more water you add the more distorted your design will become.
Unfold your paper, and voila, you have your very own inkblot. Simple, fast, but it takes a little bit of forethought and planning. Produced in multiples it could make a very fun project too. Think of all the variations you might get. Try altering the consistency of your pigment and glues. You may want to vary color, or paper quality and surfaces. Enjoy.
