I was asked this year to prepare some letterheads for Christmas letters. For the Bethlehem one, I started with my original drawing and embellished it with the Peace on Earth and a large snowbank. I'm happy with it.
This Joy to the World one involved layout and design and less drawing. I think they both turned really well.
I can start a library of these digital files which provides an alternative to what is commercially available. Of course they can be adapted to any color scheme one might like.
