You can see mine and the other six incredible Design Team members creations on the challenge post linked above, but I thought I'd offer you some more inspiration...
Perhaps the most obvious choice is the flowers themselves, and the greenery shown here is just the right amount that we'd ask for as an accent...
Or, you could choose to perhaps use some nested dies to create a repetitive background or feature element similar to this...
Last but not least, those of you who like getting inky, might create a background and pair it with a silhouette...
From all of us gals, THANK YOU for playing along! We're so thankful for YOU!
