To create enough stencils to play with, I make a stack of 32 sheets of newsprint sandwiched between 2 sheets of thin plastic posterboard. The edges are taped up and a pos/neg design is rubber cemented to the surface. The design is then pierced with a thin drill bit to allow a jewelers saw blade to be threaded though and cut away the design.
The plastic on the exterior of the stack gives the stack a workable level of stiffness. With practice, imagination, and patience, you can get pretty noodley with your designs.
I like mixing and matching stencils to create my designs. I usually start off working to create a specific composition... just to see what it looks like. But after that though, the work turns to a pure freeform and organic style of composition.
This is where I get to fall into a nighttime groove... it's all about the Jazz... the surprises of a flow...it's where the racers happen...
