A while back now I ordered a framed canvas print of my favourite thistle photo from PictureFrames.com. The print itself is 20″ square, and it is framed in a 2″ wide frame (so the whole thing is 24″ square). And it is spectacular. The photo on the right shows some of the detail; this one shows the entire frame.
It arrived the day before I left for the two weeks in Europe, and has been sitting at the house waiting for me ever since. This weekend I finally got around to hanging it (it was measured to fit into a recess area in our bathroom).
