Here is a super quick, and very inexpensive way to dress up your lamps for Halloween. All you'll need standard black construction paper, scissors, tape and the template below.
Just click on the image below to download and print out the template. (or instead of printing, open the PDF, size it 100% on the screen and lay a thin white piece of paper on your computer screen and trace around the template lightly with a soft pencil... saves ink!)
This design fits a standard small lampshade with a top diameter of 3" and a bottom diameter of 5".
First, place the open bat side of the template (see the arrow above) on the fold of a large sheet of paper (you can make one by taping two 8.5"x11" white sheets together.) cut around the template but don't cut the folded side! Cut the half bat silhoutte out. Place the template onto a black piece of standad construction paper. (9" x 12"). cut around the outside, I used pinking shears to give the bottom edge a jagged look. Wrap them in a circle and tape closed. Slide over your lampshade.
(Hint: and easy way to cut out the bat is to fold the black shade in half and then cut it out.)
These would be cute with spider images or pumpkins! (You can tape small face pieces to the shade after cutting out the pumpkin shape). Just a thought! You can also use this as a jumping off point for larger shades too.. just need larger paper or fabric.
