I have seen several of his quilts at shows and love them. What a talent! You can use a picture of anything, a bird would be a great choice, just make it a picture that you really like ( look at your avatar picture) so you will enjoy transforming it into a new medium. it might be a good idea to take several photos with you and have help picking the best one. I am just a bit jealous that you are lucky to be in this class. I would love it. Have fun.
peace
