I actually had to ask her to send me a phone pic of the card since I forgot to take my own. I wanted a unicorn dancing but couldn't find one, so I drew one. I think it turned out pretty well, so I have one here for you to download if you wanna use it for cards. Just right click on the image and download to your computer.
And here's a Halloween image from a real digi artist for free...it's from Useless Trinkets, I love her stuff. So cute! She has a unicorn too, along with monsters with coffee cups. Check it out!
If you're more vintage-y than cute, here's a great site where you can get these printable images and the instructions on how to make the garland. Free!
