I made my card for a few challenges listed on my blog. The Curtain Call Inspiration challenge is Gorgeous Gourds and can be found here: http://curtaincallchallenge.blogspot.com/ Now you see where I got my blue pumpkins. I think what we call blue pumpkins (and they're much lighter color than mine) are actually Jarrahdale Squash or Australian Blue Pumpkins. That is what I found online.
I stamped my large pumpkin and masked it to stamp the leaves going up my card. It is also paper pieced. Then, I stamped a few of the leaves to the side, stamped, colored, cut out and popped up the two smaller pumpkins.
