It is using Sweet Summer set from the Sale-a-bration catalogue. I have coloured in the images using Stampin Up's Watercolor Wonder Crayons.
The background is done with the scallop edge border punch. I saw a great tutorial for it from Mary Fish at Stampin Pretty. You can see her video here.
It's a great technique using the scallop edge border along both edges of a thin piece of card stock, with one edge being off centre.
