Last fall I collected several different interesting acorns at Daniel Stowe Botanical Gardens. One was this funny little one with a really big, intricate cap, called a Burr Oak. It is a large acorn that reminds me of a little boy with a big shaggy knitted cap with fur brim.
The photo at left is Photoshopped. I find that the Posterize filter really helps in planning different segments for value and color changes.
The sketch is my design for creating a new piece. It will be the dickens to get the templates cut and the tendrils inked. Wish me luck!
