Wikipedia defines Serendipity as a "happy accident" or "pleasant surprise"; specifically, the accident of finding something good or useful while not specifically searching for it.
This was never truer than when Karen Apps made a little paper bear as part of her MA studies. She submitted the bear for selection to show at the Turn the Page artist's book fair 2013. When organisers later used it on their publicity material it was seen by a researcher for the BBC's One Show. The researcher contacted Karen and asked her to to make something for their upcoming feature 'Fifty things to do with Fifty Shades" and, a week or so later, Karen's Shades of Grey puppet made a very short appearance on the show. (you can read more about it on Karen's website here.)
It just goes to show that you never know what the littlest thing might lead to..
