Cynthia Wenslow asked on her blog if anyone else made samples, and my anwser is YES!  Consider it a hold over from art school where we were expected to make sketches and color swatches of EVERYTHING before we even made something.  But to anwser Cynthia's question... with the cost of supplies exploding I'm making more samples than I ever have in the past.  Above is a color sample of pink on black to see if it was possible, the anwser is YES with opaque pink paint on top of black fabric.
