How cool is it to make your project actually light up! I read this article on Nuts About Needlepoint:
You can make sequins that light up using SMT LEDs and crimp beads. With these you can make needlepoint (or other stitching) that lights up. I keep thinking of a lit lamp, spooky eyes, or a cool way to highlight a letter. This YouTube video shows you how to do it.
Check out more from Adafruit.com. The video tutorial is great.
