here is what you do...before you add images and all that good stuff....turn on your coffee pot....or if you have a candle warmer turn it on...it has to be nice and hot...place a few caps on the hot part of the coffee pot..with the top (flat side) touching the hot burner. Leave on their for a minute or so...once you do some you will figure out how long to leave them there...with a a rag (the caps will be hot!!) take them off...I use a fork...just poke the plastic liner out...YOU ARE DONE!!
If it isn't working you are not leaving them on enough!!
