My mother used to press flowers in her bible, and other books.
My grandmother and I spent a Sunday afternoon on the front porch of her house in summer, many a Sunday, pressing flowers.
My Grandmother was a faith filled woman.
She taught me about faith during those pressing sessions.
This led me to where I am today with herbs, flowers, and the like.
Here’s a post about pressing flowers.
