For my LED wristband I did a sun setting. My diagram that I followed is below. The positives were connected to the positives and the negatives were connected to the negatives in order for it to function properly. I placed the battery on the right side of the wrist band and anchored it with conductive thread. I anchored the positive side first which led me to do a small cross stitch to the positive side of the LED also. When that was finished, I knotted it and then started a whole new stitch to connect the negatives.
Some tips to help you get the correct outcome would be
-Ancoring correctly (looping it 3 times)
-Making sure positive goes to positive and negative goes to negative
