I made this greeting card with some pergamano technique used for the big flower:
1.First step - sketch the flower petals and color them on the back side of the parchment sheet.
2. With embossing tool sketch the inner part over the sponge
3-4. With a needle trace the shape and then with small scissor cut between the holes.
5. Arrange the petals
6. Transparent effect on the sky background
