Sounds pretty. It's challenging to come up with something because you don't want to take away from the panels themselves because they're stunning in their own right and you want to highlight the scripture. I found some beautiful fabrics that had those peacock colors I was looking for, but I thought they overshadowed the panel. It's kind of like doing a scrapbooking page--do you want everyone to "ooh and aah" over the borders, stickers, and fonts, or do you want the pictures to be the highlight. In my opinion, simpler is best. Another thought is to use 3 out of the 4, and do something on the diagonal from the upper left corner, down to the lower right corner. Your "filler" would be on the right upper and left lower sides, also on the diagonal. Triangles? Just a thought. I'm not sure which one I could bear to part with. We'll keep this going and see what we both come up with.
Blessings to you,
