So here is a really simple and in my opinion quite nice, birthday card you can make in 5 minutes.
I kid you not!
Color Theme: Black and White, Vintage, Dark Maroon, Silver
Materials: 2 types of ribbons - 1 about 1 cm thick, the other one really thin, scrap scrapbook paper, small alphabet stickers, glue
I had just these 2 pieces of beautiful vintage black-and-white paper I've been dying to use. I usually throw away scrap papers that are not of a decent size...The bigger card is postcard-sized and the other one is about two times of a regular namecard.
So in really easy steps: Fold the paper, try to tie a nice ribbon with the smaller ribbon on top, paste down the super glittery ribbon below, paste the alphabet stickers and there you have a really nice birthday card. The more complicated the background is, the better!
