Here's a great way to have dried flowers last longer, put in a shadow box. You can make your own with any box about 4" deep that is the dimensions of the opening and cover with decorative tissue or handmade paper. There is a bunch of baby roses, blue, lime and peegee hydrangea, yarrow, berries from a palm tree in this arrangement.
This one was done years ago and given as a gift and the flowers inside finally faded. I was asked to redo the arrangement and now it's freshened up and will last for several more years.
This idea was seen in a shop years ago and it was 200.00 so I thought I would make it myself. One of those things I saw that I really did go home and make. One time I saw a sign at a craft fair in a booth and it said "sure you can make it but will you"? So true, I see so many things I could make but never end up doing it.
