When I say this color combo challenge, I knew right away.. PUNCH FLOWER!!! I like how it came together and its simple enough that I could do it in almost 10 minutes.
My combo challenge:

Stamps: Just because, Awash with Flowers (stem); CS: Marina Mist, Daffodil Delight, Peach Parfait; Oval punch, Boho blossoms, glitter
Have a great day!
