Even the most basic of materials can be turned into stamps and create some unusual and surprising results!
A cork, for instance, was used to stamp this little pumpkin Halloween stamp. I simply cut the end of the cork to make sure there was a flat surface and stamped it on paper. When it was dry I used black marker pens to make the face and made a few squiggles to make the tendrils from the top of the pumpkin. One of the interesting features of stamping with corks is that it leaves an attractive textured print on the page.

Tip: Ensure that the cork is well inked - it would also work well with paint!
