Thanks Guys.
I'm thinking of doing the pumpkin patch for it. But not sure how to make big pumkins!
Sorry, I just seen this question. Just use Green Stuff. Roll into a ball the right size then gently(I had a clay shaper with a dull point, but I'm sure a blunt pencil would do) Mark lines for the separate segments of the pumpkin. I split mine into about six. Where the lines cross at the top make a small depression. Let it dry, then roll out a very thin sausage of GS, cut and place with a knife to make your stems.

.....or alternatively, buy the ones I made for Ainsty.
