For beginners, you'll need to trace around your seal, but after a while you will be able to wing it.
Moisten your seal. You can use water, oil, or a pigment stamp that you would use for rubber stamps to make a 2 tone impression.
Light the wick.
Hold wax at 45 degree angle and drip on the circle.
Don't drip till you fill the circle...
this is too much. :)
Press your seal into the wax and hold for 1-3 seconds, then lift straight up. If when you lift up, it doesn't want to come up, leave it down till the wax hardens completely then pull up. You probably did not get all of the crevices when you moistened it.
Voila! You have made your first impression.
