Answer: Multi-Level Embossing!
There are 3 levels of embossing available to you. In some cases, your design will dictate which kind of die you should use. In others, your budget will lead the way. The larger the embossed area and the more complex the design, the more costly the die.
In multi-level embossing the paper surface is raised to multiple levels to create a 3D effect. It is best used for multi-dimensional shapes (such as the window artwork above), landscapes, or images that have unique details such as leaves or feathers.
