The first set I've used is Birthday Airplane Wishes. Friends of mine recently had an anniversary. He is a pilot and they have a Vizsla. If you aren't familiar with that breed, here is a photo of one of the Hungarian hunting dogs.
With that information, can you see why this stamp set was a good choice for making their card? Here is the front:
And here is the inside of the card. My hand written greeting went on the left, the back of the cover.
I used Tombow markers and water to create a sky background on Bristol paper. I stamped the images, then scanned them and slightly enlarged them for easier coloring with Copic markers. The images were fussy cut and glued to the sky background. The lettering was done in Word. The cover greeting used Stampin Up punches, the arced lettering of Happy Anniversary was done using Word's word art and the banner was cut free hand.
If you are wondering about these sets, here are ones that I have seen at Michaels:
