Choosing your flowers
It is important to pick flowers that are suitable for pressing. Flowers with a low water content will both dry faster and look nicer pressed, as they are often thinner.
What to press them in.
As you are pressing all the water out of the flowers, be sure to choose something that can absorb the water, such as a book, newspaper or a piece of cotton placed both above and beneath the flowers.
Find something heavy
Find something heavy to place on top. Be sure whatever the item that it distributes the weight evenly over the surface it is pressing against, to help ensure your pressings come out evenly flat.
Leave the flowers undisturbed for around 14 days.
Once finished all that is left is to take your frame and start arranging.
