I'm drawing the line. I've boiled this pot of invasive Dame's rocket FOUR times now and the stalks are still tough. It may be one of those plants that will only break down using lye, and I don't want to go down that road. I love that the majority of steps involved in this photography project are organic and don't require the use of anything stronger than soda ash and hand sanitizer. However, lye is another story. For now, I'll stick with the more user-friendly invasive plants phragmites and garlic mustard for my paper-making.
