This card was completely out of my color comfort zone but I really like how it turned out!
To make the white lines, I first drew them freehand with pencil, then pierced along those lines, then connected the holes with the white gel pen.
The left piece of green is created by punch out the flowers (staring in the middle works best) and then putting the green with the 8 flower holes in it) over the blue and letting the blue show through.
