Measure a piece of wick that is about 1 inch longer than the jar.
Insert the wick into the tab, pull it through and wrap about 1/4 inch around itself on the other side.
If using the sticker, add the sticker to the bottom of the tab and then gently press the sticker with the wick to the center of the bottom of your jar. Press down gently to stick it well.
Using the glass 4-cup measuring cup; In 1 minute increments, melt your soy wax with 1-2 pieces of colored wax chips (the amount you use depends on the deepness of the color you want--a little goes a long way!) in the microwave until completely melted.
If desired, add several drops of essential oil and stir well.
Carefully pour the hot wax into the jar (be sure to hold the wick up so it doesn't fall into the wax) until the candle is the fullness you want.
Either hold the wick until the wax has set enough to be firm OR use a clothes pin and pinch the wick in the very center of the clothes pin and set the clothes pin across the jar OR use a wooden skewer and twist the wick up around it until tight and set the skewer across the jar.
Let the candle cool completely over night before using.
