When you lift the paper off the burnt material, you have beautiful and subtle grey-black and amber marks on the paper (rinse the paper off with a hose). The element of chance governs the patterns; you can control it some by how you lay out the straw, or what materials you burn. But it is always a surprise. You can do the process more than once to get an effect that you decide is "done." Once the paper dries, you can use it to paint or draw on.
