COLORING EACH TREE BY HAND

Here's what the finished print looks like.  I added my signature stamp to the back.  

I got out my colored pencils, mostly Prismacolor and sharpened them up.  I'm putting a green all over the tree first - "Grass Green",  then highlighting with some blue-greens "Aqua Green" and "Parrot Green" and a yellow-green "Chartreuse".  The 'lights' on the tree are "Canary Yellow".

Dang...the "Grass Green" keeps breaking off... I don't know if it will last through all the trees.

Here's the finished card.
