There's a reason why the word "witchcraft" has the word "craft" in it; it's because both crafting and witchcraft require making a lot of precise cuts.
Of course the Silhouette Cameo 3 isn't great for witchcraft. It can't help you cut out an eye of newt or divvy up any of those potion ingredients you've got lying around. But it is GREAT for regular crafting. Like, if you were to, say, hold a coven meeting, the Silhouette Cameo 3 wouldn't be very helpful for the meeting. But if you want to make some sweet stickers and posters and scrapbooks for your coven, this is the machine you're looking for.
