First, I found a thin piece of chipboard (this piece came in a package of Stampin' Up patterned paper.) I trimmed the chipboard to be slightly larger than my card front. Then I used a star punch to punch 6 stars from the leftover chipboard. I arranged 3 of the stars on my chipboard base, then adhered them down. Because the chipboard was so thin, I stacked another star on top of each on the base and adhered them so that I could get a deeper impression.
Then it was time to emboss. It took a little trial-and-error to come up with the right "sandwich" for my embossing plate, but here is what worked for the thickness of chipboard that I used. You may need to adjust your "sandwich" if your chipboard or cardstock is heavier than mine. I started with Tab 1, one clear cutting pad,and the homemade embossing plate. (Make sure the star punches are facing UP.)
Next, I stacked my kraft cardstock on top of the embossing plate, making sure that the edges were placed slightly inside the edge of the embossing plate.
The next layer is the black silicone pad that I use with my Sizzix embossing plates.
The final layer is the hard black plastic pad, also used with the Sizzix embossing plates.
Carefully run all layers through your die cut machine. Here is what the finished cardstock will look like:
To highlight the embossing, I rubbed a Creamy Brown chalk ink pad over the tops of the stars and also around all of the edges of the kraft cardstock. I attached the embossed panel to the front of my card base, then embellished the card with rub-on letters and a handmade bunting embellie.
