It's finished!!! Once again I have to thank Lucy at
http://attic24.typepad.com/ for her wonderfully clear tutorial so that even beginners like me can make Stuff-That-Looks-Really-Complicated!
This first version is destined to live at the Country House and later this week I plan to start another for the Week Day Home. It didn't take too long to make once I got going and the really fun part was stringing it all together and deciding which beads to use. Let me know if you have a go at making one too :)
