i remember as a little girl collecting all sorts of flowers and leaves and stuffing our old school, massive phone books with them. those old phone books were ideal for pressing flowers, as you could fill them with quite a collection and the paper was perfect. plus, at our house anyway we had a huge stack of yellow pages and white pages.
redtedart has a great tutorial on how to press flowers. it’s really not hard and you don’t need any special equipment, except maybe some patience as the flowers take a few weeks to press and dry properly.
when travelling, i have picked a flower and placed them into the book i have with me. sometimes i have forgotten about them and rediscovered them a while later. what a lovely way to reminisce about an exciting adventure!
