For this holiday season, add a little glitter to your home or crafting/work space with your own LED Felt Decorations. No need for soldering irons: The simple LED circuit is entirely sewn by hand using conductive thread.

You can use the provided template or venture off on your own by designing custom shapes and forms.

LED Primer
Before you go to your local electronics store, there are a few things you need to know about LEDs (Light Emitting Diodes). LEDs are tiny lights that emit a bright light while consuming very little power. The reason they're so cool is that we can run them off of small batteries.

A typical LED has two leads (legs)  one shorter than the other. Just like batteries, LEDs have a positive and negative side (or lead). The shorter lead is typically the negative while the longer lead is the positive. In order for the LED to light up, the positive lead must be connected to the positive side of your battery while the negative lead to the negative side of the battery in order for the LED to light up. If you reverse it, it simple won't work.

Grab your 3V lithium battery and try it out. Touch the longer LED lead to the positive side of the battery and shorter to the negative side of your battery. Your LED should light up! It's really that simple.

Now that you know how a simple LED circuit works, let's start crafting.

Step 1: What you'll need:

Conductive thread
1 x metallic snap
1 x jump hoop
1 x 5" x 5" square of 1/4" industrial felt
1 x 3-5 mm LED
1 x 3V coin cell battery
1 x sewing needle
1 x needle threader (optional)
Industrial Felt (or other thick material)
Crafting knife
Needle nose pliers
Tracing pen
Hot glue gun
Black marker

This thing scares me... it's gonna eat my soul!
Ah, soul.
 white colored light might be better. the red kind gives it the "evil robot" look. neat idea though. 
Yea but then it would be a little bland and not Christmasy.<br />
How about green? That's pretty Christmassy, and less evil.<br />
I dunno... Green doesnt sound like a color for an eye...

I was suggesting green as you wouldn't have to increase the voltage that the LED uses - blue or qhite LEDs usually need a higher voltage to power them, which might mean you need another coin cell.</p> <br /> <p class="MsoBodyText">Blue would be nice (though maybe a bit &quot;cyborgy&quot;). How about yellow or orange?</p>
Well yea but then it would blend into the tree...&nbsp; Lol my preference would be blue.<br />
Uhhh yeah the red eye makes it look like an EVIL dove... A blue led might be better...
&nbsp;ha. i agree but unfortunately it's a little difficult to get most blue LEDs powered by a tiny 3V lithium battery. Typically they require at least 3.4 V...
Well then if you wanted you could use a 3v and a 1.5v with it...
AAAARGH! :)<br />
No, doves. They are much better. Prettier, better coo, they laugh, less poop.
Where can one find industrial felt? I just figured the battery out. A picture of just that would have helped. I love the switch. It has been hard for me to figure out things that are not always on.
You can buy industrial felt from your local Osh hardware store (if you have one in your city/town). Osh only carries the natural white/beige or grey felts. <br/><br/>If you don't have an Osh near you try here:<br/><a rel="nofollow" href="http://www.nanricstore.com/servlet/the-198/1-fdsh-4%22-felt-cast-padding/Detail">Nanric</a>Nanric<br/><br/>Or online at: <br/><br/><a rel="nofollow" href="http://filzfelt.myshopify.com/">FilzFelt</a>FilzFelt - Nice variety of colored Felts<br/><br/>Other resources can be found <a rel="nofollow" href="http://fashioningtechnology.ning.com/page/page/show?id=2095467%3APage%3A1050">here</a>here under Industrial Felt.<br/><br/>Hope this helps! <br/><br/>Also you can substitute the industrial felt with any other dense material that you can sew through. You can layer a number of textiles together and use ordinary felt if you wish as well. <br/><br/>
