Pressing Flowers is a very calming activity. You can do as a hobby or to create arts & crafts to sell. Besides reading, pressing flowers and creating artwork with them is my hobby. So here is a list of what I use (or wish I could).
This is the books I have to learn best techniques. But its beautiful and it reads like a magazine, very relaxing just to sit and read.
