What to do with old flowers?

my boyfriend bought me amazing flowers for valentines day.
roses, and tigerlillies [[my absolute favorite]]

what can I do with them, theyre starting to wilt and die,but I want to keep them.

YOu could dry them upside down. They stay pretty forever, just dried. You can't keep them from drying.

you could hang you're roses upsidedown, and you could take your other ones and place them in a book... I always tell my boyfriend, never get me roses because they die to quick,.. and are way to expensive... and I find just normal flowers mean just as much, And last way longer.

you can use put it in a think book and let them dry. this way they will dry flat and you can put them in a photo frame :D

I heard if you use hairspray on the flowers they last a while...
