Recently my friend Jackie sent me several links to cool Halloween projects. That's how I found the Ink Stains blog and the directions to make a cool stamped and decoupaged pumpkin. I loved this project! I did half of it last night and had to let it sit and dry before I could do the other half, and all night long I was kept waking up and thinking about finishing it. That's how much I loved it. (However, I didn't love not sleeping well!) I won't give you the technique here since it's not really my technique, but you can find detailed directions here.
I used these rubber stamps by B-line Designs, Tim Holtz Stampers Anonymous and the cool vampire bat in the center is from Paula's Kit Club. Here's a close-up.
