AddieLou, depending on how many you have done so far, maybe you could put the scrappy ones in the middle and then surround them with the ones with the white bkgrd. Or use the scrappy ones in the border if you don't have too many of them, with a thin (1/2 to 1") solid color border between them and the ones w white bkgrd. If there are not enough for the whole border that is fine having them at the corners, 2 on one side, 3 on the other at each corner. Whatever works. I think I am going to put 3d pinwheels in the corners of the borders.
Hoppyfrog, all I have to say is WOW! are you productive. I'm impressed. :^) Marcia S. in TX.
