Hey Guys welcome to our Entry for the Sew Contest Ins. We made an Electric Heated Sweater that uses a 9v battery to heat up your sweater. It works great yall should give it a shot. Just make sure to follow the instructions and you use a sweater that you dont really love! cuz you wont be able to wash this sweater EVER AGAIN!
Important safety point: only use this is a pure-wool sweater, or one with proven heat resistance. Many synthetic fibres melt at surprisingly low temperatures

Step 1: Getting Your 20 Gauge Wire
You have to meassure your 20 gauge ENAMEL copper wire to your desired lenght. Usually about 5-6 feet. This really depends on the size of your sweater :P
Step 2: Start to Weaver Your Sweater With Your Wire
The next step is to start to weave your sweater with your copper wire in a zig zag motion. You will be using the Copper wire instead of a needle and thread Start your weave from about 1" from the top and 1" from the left shoulder. (or right depending on how you look at it)
You have to make sure that you weave in between the two layers of your sweater, you dont want it to make contac with your skin or you could get burned, very unlikely but it could happen.
You need to go all the way to the right (or left) then go down 1" and come back to the other side, then go under again 1" and go back. repeat this process till you get about half way down because anything bellow that is more of a hastle than anything.
you will end your zig zag at the bottom right and then weave your way to the top to about 1" by 1" from the corner.
Step 3: Repeat Step 2 on the Back
YOu need to repeat the sames steps on the back of the sweater in the same pattern (zig Zag)
Step 4: Connect Your Copper Wires
Connect your copper wires from the back of your sweater and then connect them to the front using a 9v battery connector.
Step 5: Attach a Switch
you need to cut one of the wires on your 9v holder and install a switch
Step 6: Make the Pocket and Put the Battery In
Make a small pocket to hold a Small Tin Can inside it. You dont have to do that but we REALLY recomend you using a small tin box just in case the battery explodes or something ( we have had our sweater for 3 days and it still has nothing wrong)
Attach the switch onthe side of the tin box and place it inside of the pocket. You need to then hook up your battery and put the battery inside the tin box and close it.
Step 7: Turn on Your Switch and Feel the Heat BABY!
once you get the switch on the ON possition you will feel the coil begin to warm up after a couple of minutes. It worked great and it actually can get pretty hot but it works amazing.
Specially if you wear a jacket over the sweater it works better and it hides the battery. The coil can only be seen from an angle or under extremly bright lights. Enjoy your new sweater and hope you like it ! Dont forget to visit our website at www.hm-innovations.com
