Pressing flowers is a wonderful way to preserve their beauty, and the process couldn't be more simple.

For beautiful pressed flowers, gather clean flowers free of spots or blemishes. Try collecting them on a sunny day when they are not wet from rain or dew.
Place the flower face down in a telephone book lined with parchment paper.
Close the book, weigh it down, and leave undisturbed for seven to 10 days. You will want to check to make sure all the moisture is gone and your flower is papery.
