Do a small area at a time allowing the wax to set in the area that you are working before moving on to the next area. To get the terry cloth look, use only the tips of the bristles.

Final dips are an options but are personal prefrence.
Final dips should be done around 180 degrees for one final quick dip. This will result in a satin finish and shouldn't affect the final appearance too much. If you want to dip more for a smoother finish dip at a cooler temprature and dip more often. This will help smooth out the appearance of your cacke or primative candles. You can use herbs, dried flowers, oatmeal, cornstarch, sand, rice krispies, even crushed candy.
