The dimensions I ended up with were 3 1/2 x 3 1/2. I used Night of Navy cardstock, Bella Rose DSP (the green with white dots), and white taffeta ribbon. I also used some Doodlebug rub-ons to put her name on the front and the card amount on the inside.
This week is her baby shower (and another for my neighbor, Stacey). I'm excited to do a cupcake bouquet for each of the showers. I've seen it done, but this will be my first try. I've painted and stamped a pot to use too, so I'll post on here afterwards so you can see how it turns out!
