Step 5: Sew "wiring" into place
At this point, the gloves look identical to the picture my sister originally showed me. But we'll take it a step further. :) I've included a schematic of how the wiring will work on the gloves. The purple oval represents the battery holder in the images. The yellow dots represent the LEDs.
While wearing the gloves, touch your hands together to form the heart. Try your best to find our where the best point of contact is between your hands. Mark this area with a pin.
Flip the glove for the right hand inside out and sew down the battery holder. Be sure the positive and negative side corresponds with the schematic.
Now, begin to sew the circuit down starting with the positive line coming from the battery. You don't need to start here, but it's the easiest to do, so we'll practice with it.
I found it easier to sew with the glove inside out. So I also included a schematic of how the circuit should be sewn in from the inside. The gloves I used had enough stitches for me to be able to sew in the thread and not have it show up on the opposite side. If you can do this, it will make for a nice, clean look on your gloves. The trick is not to poke the needle in too far.
Once you get to the edge, you should be able to see the pin you placed to signify the point of contact with your hands. This part can get tricky. Sew the thread in 1cm lines around the pin. This will ensure that you're sewing the thread where your point of contact is located on your hands. Sew these lines several times. When you finish doing this, you should have formed a sort of rectangle with the thread. See the images as a reference.
Continue these steps for the rest of the wiring. When you make the first stitch on the edge of the hand for each hand, gently put the gloves on and make sure these stitches touch the point of contact areas on your hands. This is very important because if your stitches don't touch, the LEDs won't light up.
