Haha, from one blonde to another, dont feel bad, 
as I too have been fooled by the crafty 'ninja 
layer'..

I got a new cel from a shop once, and I saw it 
had staples in it.  The cel was so clean, and 
there was only one number in the corner.  I 
thought, who puts staples in a cel with one 
layer?  So, I began to remove a staple...and 
swish...the small second layer falls to the 
side!  It was the mouth on one of my ANC 
cels..which is just a thin line, so I didnt even 
notice it was seperate.  Now I need to go replace 
the tiny staple...that is driving me insane!
