The dried flowers are beautiful between the panes. Without the lichen (desiccant), keep an eye on them when there's condensation.

I grew up with single pane glass windows. With modern windows, I miss the frost patterns in the morning. My room faced East ... so the morning sun would shine through the frost and at certain moments of the morning would cast patterns on the walls. Staring at these patterns did not help to motivate me to get up and ready for school. ;-)
