I love that color combo! I saw a treasury with these colors...pretty sure it was made by junkyardgypsy, who has quite an eye for making treasuries...and I loved it! (Of course, I love all of her treasuries! ;) Then I bought these new stamps. It's a set of 4 with trees on them. I took out my cardstock and started brainstorming. These 2 colors really stuck out at me, so I gave it a whirl.
For right now this card is not for any special occasion. However, if you really like the card but want something on it, such as "happy birthday," I am happy to do that!
