BRT, I think what strikes me about Gwyn's is the swag and heart borders have soft fluid shapes and movement which are perfect for the tree hearts of the center. But then my eye comes back to the purples/blues/greens of the center and those are in very linear geometric shapes. What about a piano keys border with the shades of the purples/blues/greens? A separation would be needed between the hearts and piano keys, similar to the dark border that surrounds the center perhaps. Like Patti said, I'd think bringing the background colors into your border would be very nice. I'm sure whatever you do will be lovely. You do such wonderful things!
