This is a lady slipper orchid that I saw at the Meijer Gardens Butterfly exhibit a few weeks ago. I did work from a photo since I didn't have time to sketch while we were there. I loved the rounded and curled petals and leaves.
I started with just a rough sketch and then decided to go over it in pen and ink. I wanted to add some color since it included such a beautiful purple, so I went over everything with colored pencil. I used three colors in most areas, except for the green stems (just using two there.) It was a relatively quick drawing that I did last night, so I was pleased with how it turned out.
