Ahhh, it may indeed become addictive!
Here's another mosaic, the common theme for this one is supposed to be red and blue.
I'll need to upload more photos to flickr for yet more selections... but not tonight!
Now I'm going to switch off the computer so I can concentrate on my granny squares. I've done eight of them so far so I'm half way through my cushion cover.
Hmmm, granny square photos will make a nice photo mosaic...
