I saw this idea from Family Circle October 2011 issue. I LOVED the white 31 pumpkin and downloaded the template for it from the Family Circle website.
I didn't have the specialty rub-on paper to make the pumpkin in an easy one step process, so I created a cheaper 3 step process...
1. I printed out the 31 on my ink jet printer and was able to rub enough of the ink on so that I could see the number on the pumpkin. I used a Popsicle stick for the rubbing.
2. I tested my sharpie on the bottom of the pumpkin to check for any bleeding effects. The sharpie worked great with no bleeding, so I used the thin sharpie to outline my rub-on.
3. Using my thicker sharpie, I filled in the number 31. I am loving the end result!
Bring on Halloween!
