I have a folder for greeting cards I was given once, that has a page for each month where you can write down who has a birthday or special occasion, and there's a pocket on the facing page to store the cards for each month. I use that for the cards I've made, and recently found this one among my craft stash (I have a whole cupboard full of stuff) - so I had made it ages ago (literally years) and never used it!
I had some cat stickers on a little sheet that also had some flower stickers and I decided to mount them on a piece of pink card, which I put on top of a strip of pink ribbon that I stuck two thirds of the length of a tall thin card blank. I used some more of the pink ribbon along the bottom and mounted another piece of pink card on that, with a 'have a great day' sentiment sticker. Great for a cat lover like me!
