The stamp sets used are Key to My Heart and God Bless You. The paper is from the Apsen paper packet and the colors are Twilight, Outdoor Denim and Colonial White.
For the key, I first stamped it in Twilight ink and rolled it around a bit in the Outdoor Denim ink to give it the different colors look it has.
Then on the inside, I wrote about how God will always be the key for your whole life. =)
