This is a great layout--I love being inspired by the sketch challenge. Rather than using the flat edges, I decided to use scallops to create a more intimate "meeting" ground for the birds. It's almost as though you are peeking through a window to see them.
When I first saw the sketch I picked my patterned paper and it set the tone for the remainder of the card including these ADORABLE birds from the Kim Hughes Collection at Cornish Heritage Farms.
