For the birthday and thank you cards, I began with this design, which I originally found on Pinterest. It lent itself to scraps, so I began by going through our scrap box, pulling out all the pieces which might work. I then paired them together. Here's some of what I came up with.
The top is a Cuttlebug embossing folder. The ribbon is from my stash. I found the star brads in the cupboard; it's been a long time since I used brads!
Here are two of the feminine cards. The heart on top of the ribbon is from the Decorative Photo Corners set by Spellbinders.
The thank you notes have all been sent - except for one - but I still have plenty of the birthday cards.
