This first version was done all in Picasa, while the second one was done in Photoshop. The Picasa version was practically instant and not jaggedy edged. I like it better.

 

The first one has been brightened and the second one has not. Your choice.
As you know you can click on the image and it enlarges, twice.
Below the first one done in Photoshop and the second in Pinterest. I could clean that one up a bit more. Of course in Pinterest I am cropping and that squares up the sides. Won't work with an uneven quilt.
