I had my old medical book so I tore out some pages:
Then I rounded the edges to make a pumpkin shape.
This gap in pictures is where it got tricky. Finally I figured out I had to staple the pages together and then tape the stapled pages together with other stapled pages.
And then I realized I needed way more pages.
I misted the pages with some ink (I only had red but then after realized I also had yellow, oh well). Then I hot glued a twig on with some fake leaves.
It doesn't look as cute as the original and it took way more time than I thought. But still fun to do.
