Mystery projects

Today's SBQ was suggested by Carol and is:Q. 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 participated in one mystery and that was JARDIN A DECOUVRIR...
from ALPC, this was because it was a garden, I really enjoyed doing this very much, I stitched mine on pearl evenweave and all the flowers are stitched in 'Love' and that was literally as I used WDW 'Love' as I liked the colours that was in it. The house was stitched in Kates Kolours in mellow yellow which was very subtle shades of warm yellow. This is one I framed myself again and it was one of the one-offs from my LNS its a yew frame.
I signed up this year to do Chatelaines MysteryIX again as its a garden, but as yet I haven't started it, partly because I haven't had the time, partly cos Mark really doesn't seem to like Martinas designs (I don't know why - he says they remind him of an old maiden aunts house???????) but I will do it regardless of that comment, and lastly the other reason I haven't started it is I can't afford it as I want to do it in the silk threads etc.
The other 2 mysteries I have been going to start is the Quaker 6-monthly one and also the Quaker design in the Gift of Stitching, I will start either of those soon and play catch up.
