You can see mine and the other incredible Design Team members creations on the challenge post linked above, but I thought I'd offer you some more inspiration...
Keeping things simple, you might want to emulate a precious ring by using blue rhinestones to accent your design, with or without the addition of clear ones...

Or, you might want to use your inks to create a feature background...
From all of us gals, THANK YOU for playing along! We're so thankful for YOU!
