This heart was created for a "Crafty Chicas" workshop at the Lower East Side Girls Club, February 12, 2011. Happy Valentine's Day!
Study the LED. The LED is bipolar, with a positive (+ or anodal) prong and a negative (- or cathodal) prong. Usually the positive prong is longer.
Study the battery. The positive side is marked with a "+" sign, while the negative side is usually unmarked.
Determine the polarity of your LED by holding the battery between the LED’s two prongs. This project mostly consists of sewing conductive thread to connect the positive sides ...
Cut three felt hearts (two are shown below): 2 same-sized hearts, about 3”x5” 1 smaller heart to hold the battery, about 2”x1”
Thread about 1.5’ of conductive thread from a needle. In the center of one larger heart, sew at least 20 loops to make a nice thick knot, which ...
Thread about 1.5’ of conductive thread from a second needle. In the center of the smaller heart, sew at least 20 loops to make a nice thick knot, ...
Stitch the battery heart to the pillow front with the Negative Thread.
Poke an LED into the top of the pillow front. (If it's hard to poke the LED through, use a needle to pre-poke holes). The LED's positive prong ...
Stitch the Positive Thread and Negative Thread close to the LED. Tie the Positive Thread to the LED's positive side. Tie the Negative Thread to the LED's negative ...
Now let's test the light. Lay the battery, positive side down, on the pillow front's center knot.
When you press the battery heart to the battery, the LED should light! If it does not, make sure that none of the positive connections (thread and LED ...
Poke the rest of your LEDs though the pillow front in a design that looks nice to you. If you're short on time, use fewer LEDs.
The back of the pillow front will now be a bit messy. You'll need to be careful with this when you connect and test each light-- always make ...
Repeat steps 9-11 for each LED. If you test an LED and it doesn't work, check your positive and negative connections. If the LED still doesn't work, replace ...
When all lights are connected and working, stitch the Positive Thread to the pillow front's center knot. The Positive Thread should now form a closed loop. I've drawn ...
Stitch battery heart to the pillow front using the Negative Thread, and then stitch the Negative Thread to the battery heart's center knot. The Negative Thread should now ...
Finish off the pillow front by gluing the LED prongs in place. The glue not only secures the LEDs, it also insulates their prongs.
Now for the easy, non-electronic tasks. Sew the pillow front to the pillow back (the second larger heart), stuff it with cotton, and sew a cord to the ...
