Birthday banner with collage and stamps

I've been working on this birthday banner for my best friend Christine for the past couple days, and I finished it last night! It is double sided so it can either be hung in a large doorway/opening, or turned around to the non-birthday specific side and used at any time of year.

It says, "Happy birthday Christine!" in gold sharpie. It is easier to read in real life.

I stamped white card stock with bingo stamps that I got on a recent trip to Florida where I went to bingo night with my aunt. Then I put purple "HAPPY BIRTHDAY" stamps on top of that with a label stamp that can spell out anything. I colored white ribbon gold with a gold sharpie.

The back is collaged with prints, flowers, and hearts.

This was the back of one of the collaged sides, and I tested out a stamp color on it (which I decided would be too dark), but I thought it was a beautiful composition, even though it was unintentional.
