Any artist will tell you that designing and developing their art is a process.  I think the process is where the magic is.  It's where a change in your hand, posture, mood, grip or pressure can change the outcome, which makes each one absolutely different and unique. Not one piece of art is the same from the next.  

Here's a glimpse of me creating my art in this video: handstamping 20 envelopes for halloween stationery.  As you can tell no one is the same because each one is stamped one at a time.  My hand position, grip and pressure changes with each stamp.  Enjoy!
