Here is how I achieved my effect.
I created a stamp by tracing and then carving my image on some dense material called Speedy Carve that I purchased at Michael's Crafts.
I attached the stamp to the back of a styrofoam tray that grocery stores often use for packaging by pinning the stamp from underneath with some straight pins.
Here is a photo of this process using a sample stamp that I first created to try out my technique.

I then pinned the sheer fabric over the stamp.
Next I rubbed over the image with a shiva paint stik. I did this lightly as I wanted a translucent effect.
Here is how it turned out!
