Experiment Part Next!
OK, here's the next part...
I inserted a (moisturized) dried leaf between the dryer sheet and the angelina. I have not yet basted the layers. The leaves are crumbly (although the flower petals dryed more flexibly), so I slathered this one with hand lotion and let it sit for a bit. As you can see, the leaf is now completely flat behind the dryer sheet. I'm going to then baste the layers with red thread (easier to see) and observe how well the leaf can be viewed through the dryer sheet after basting before I determine my next step.
