With a lot of poking around, the template can be found here. It took me FOREVER to find it and I didn't copy a link directly to the pattern.
So, since it's free and I did my best to give credit where credit is due, I don't feel bad about posting the pattern here and making it easier for you. I also added some pieces because I just couldn't get mine to look like theirs. They must have taken a lot of time shaping theirs just right... Mine isn't exact, but here is what it looks like:
I can't post the Silhouette cut file here for download but if you ask in the comment section, I will e-mail it to you. (For free!)
Here's the instructions:
Here's the pieces all cut out. (If you're using a Silhouette or other cutting machine, I used an 8" strip of orange paper on the right, and a 4" strip of paper on the left and cut both colors out at the same time.)
If you don't have a cutting machine, you can copy this pattern and size it to your preference and cut it out by hand. (Uggh. That's what cutting machines are for!) For the size I made in this tutorial the pumpkin piece will fit on an 8 1/2 x 11 piece of piece of paper. (If you make it to fit a 12 x 12 piece of paper [or card-stock] then it's much easier to glue those flaps!)
side note: the flourish on my leaf is from the Silhouette Design store so I can't give it to you. The name of the file is: Pumpkin 3D Chunky Form by Snapdragon Snippets. (I'm not entirely sure this link will work.)
fold and glue this piece together.
Insert it in the cut out square like shown and glue the tabs down. This is the right or front side of the paper.
Turn it over. This is the wrong side of the paper and the inside of the pumpkin.
The flaps on the diagonals all have a score line on the tab. Fold the score line as shown and glue it inside the corner of the green center piece...
...like this.
Glue all four corner flaps. You will need to hold the tabs while they dry. This can be tricky and frustrating. sorry = (
Next, glue the remaining flaps. Again, tricky and frustrating. = (
All the flaps are glued in place (and staying there!) = )
Wrap this piece around a pencil or something slightly smaller than the hole in the pumpkin...
...like this. No need to glue it. (By this point, you're probably sick of glue.)
Place this rolled paper down into the hole of the pumpkin.
Twist the top to look like a stem. (or pinch and bend..)
Add the leaf and it's done!
This is my favorite paper pumpkin. = )
