I love Pinterest.com ideas for mason jars and ruffled lamp shade.
I purchased the lighting unit at Lowe's. I glued Spice Cake fabric to the lid (this particular lamp was a Christmas present for my friend Kim, who loves blues and browns, not to mention Spice Cake anything).
Here's the finished stamp lamp. I like the strings popping out from the ruffles. You can always finish the material edges if you don't. I basted down the middle of several 2-inch strips of Spice Cake fabric and tugged on the end strings to make the ruffles. Then, starting at the bottom, I used a hot glue gun to adhere the ruffles, making sure the seams didn't all line up for a more natural look.
I have a ton of retired Stampin' Up! sets in my studio, so I grabbed a couple of them to fill this quart-sized canning jar. You can always unscrew the lid if you want to use one of the stamps in the jar! lol I hope you like it! I still need to make one for myself.
