Happy Halloween pop-up

So, I love Halloween, and I can't get enough of it right now. I'd been wanting to make a free-standing pop-up card ever since I saw one of Dawn Griffith's YouTube tutorials. They are so easy, but produce such a great result! One of my Cricut secret sisters sent me this cute spider stamp, and I was so excited to get to use it. I embossed the background with the Cuttlebug spider web embossing folder. I made sure to use a white-core paper; when I embossed it, I placed a piece of carbon paper on top of the orange paper inside the embossing folder. The black carbon transferred onto the orange paper, then I sanded all the raised parts to reveal the white core. Papers are Making Memories, spider stamp is Stampendous, happy halloween stamp is Studio G, ribbon is American Crafts, white gel pen for doodle dots, Staz-on black ink.

Here's what it looks like closed and ready for mailing:
Here it is free-standing:
