I thought I'd share another idea using the Designer Buttons with you today...
The Button Buddies stamp set on page 34 of the main catalogue has some great stamps and all of them are designed to fit the Stampin' Up! buttons, although you can of course create plenty of designs without these too.
I recently made a couple of very quick birthday cards using the 'vase with flowers' image from this set, and had a play with some different colour combinations. Wisteria Wonder, Rose Red and Whisper White, with the flower buttons from the 'Subtles' collection. And for the second card, Bashful Blue and Perfect Plum.
I find the Stapin' Write marker pens are ideal for inking up stamps with more than one colour and makes it very easy to create cards like this quickly and in a variety of colours. The sentiments are from the Petite Pairs stamp set, which has lots of lovely words to add to your cards and which I can highly recommend (a close second to the Teeny Tiny Wishes sentiments).
