Zipper Effect

I call this the Zipper Effect (for obvious reasons).  I have to tell you that when I showed this to my husband and said "I love doing these", his response was "and I love looking at them".  If you are acquainted with my husband you will know he had his tongue shoved hard into his cheek.  He really just doesn't get the "design" aspect and his idea of Zenning is a long foray deep into the woods.  To each his own for sure!!!
