This soft LED light pouch is easy to make and runs with two AAA batteries. The design is super simple and fits really well with the LilyPad components. Though you can also modify a regular LED and slide switch to be sewable by soldering little loops on the end of their leads. The light is cute and small and soft but not really bright enough to be used as a headlight for biking so I'd appreciate suggestions as to what else it could be used for.

Copy the stencil depicted in the photographs. The measurements are important so that the pouch will fit tightly around the two AAA batteries and make good electrical contact.
Using a fabric pen, that will disappear over time. Trance the stencil onto the

Step 3: Iron and fuse conductive fabric

Adhere the fusible interfacing to one side of the stretch conductive fabric and cut out small rectangles about 0.5 x 1.5 cm in size. Then fuse these to the neoprene (the side which will become the inside) as shown in the photos. Be careful not to use too hot an iron or it will fry the conductive fabric. A slight gold discoloration is normal.

What a perfect battery holder. It's just right for the needle-felted, joule-thief lizard I've been working on.

Other ideas if not headlights for bikes... shoulder and leg "side" lights on riders for a bit more safety.

Teddybear armband lights for the comfort of small children afraid of the dark.

Velcro wrapped "throwies" or "utility belt" props for stylish Bat-girls.

Furniture "warning lights" with dark sensors. How many times has someone banged their shins against the couch in the middle of the night?

Waterproof 'em, make scuba gear "buddy lights."

(Put more LEDs on one battery pack and they become more usefull.)
