I was able to find what I wanted with the Yellow Lady Slippers. Mostly at the Headlands (just West of the bridge) and at Thompson's Harbor State Park (just North of Alpena). The ones at Thompson's Harbor were more abundant and the ones at Headlands were bigger. For the most part I am printing these on a translucent paper that is a lot like rice paper  -  stop in at one of my shows and ask to see the magic trick.
