I saw this idea about a year ago and I cannot remember from where... so sorry! If you are the talented stamper who shared this fab idea with everyone, please let me know so I can give credit where credit is due.
This is a very simple project and my boys LOVE them. The faces are one of SU's Decor Elements- page 10. You get all three faces for $4.95! Love that. I found the glass blocks at Hobby Lobby- finally! I had been looking for them everywhere. They have an opening in the top. I bought strands of 35 mini orange LED lights (because they don't get hot) from Michaels. I applied the faces to the front of the blocks and inserted a 6.25" square piece of cardstock vellum inside so it would help hide the actual string from the lights. I then shoved one strand of lights per block inside and viola! A super cute and easy Halloween decoration. And these jack-o-laterns won't rot and stink by the time the 31st rolls around...
