The dried flowers

I tried to collect the dried flowers and leaves yesterday. They were slightly damp from rains here. It has got a nice texture. I really wish to make these leaves transparent. I mean to say, like those leaves u find sometimes, sieve formed with a mesh of veins. It really looks very beautiful.
Also i still don't know how to dry these flowers without causing them to wrinkle. In one flower show i have seen dry arrangement. The flowers had not wrinkled. I still wonder how they did it. Now i have got this opportunity to try it out myself, so i will.
