SBQ

I stitched a bit on Santa yesterday , and started trilogy's Seaology last week, but haven't taken any photos yet.

SBQ:
Have you ever participated in a needlework mystery (i.e., a design that you started before knowing how it will look in the end and by which you receive parts of the design via the internet, magazines, or leaflets at spaced intervals)? If so, why did you decide to do the mystery? What appealed to you about it? Did you enjoy it? If you have not done a mystery, would you ever do one?

I have never done a mystery, up until a year ago I did not know what one was. The ones I have seen are a bit expensive, and just haven't appealed to me.
