Joanna...
what an absolutely gorgeous collection of dried plant material. Isn't it amazing how well the leaves and flowers dry and makes a wonderful way to pass thru the winter or any time for a fix. Winters can deprive some of us of the greens and florals that thrived in our gardens, some buried under snow others stuck in winters barrage of a cold grey cover.
I think you have the materials to make a beautiful collage.
Just a little one to start. I bet you can put some of the material into a nice illustration , collage or what other ideas may pop up!
Thanks for sharing I love it! Made my day!
