I received a silhouette cameo for my birthday and have been experimenting with what I can do with it. As you can see it perfectly compliments Karen burniston and Elizabeth craft designs products.
I have to say I am very impressed with it, I was able to make and cut the circular-ish shape around the Elizabeth craft design peel off balloons. Which when I tell you now, sounds easy but it did take me bit of faffing and tweaking to get it to fit around the balloons so that they sat in the centre of Karens circular accordion die.
The silhouette cuts and if you remove the blade and place one of their sketch pens in the blade slot you can make it write what ever you tell it to. I was able to create the circular wording and the '21 and holding' on the purple part of the card.
