I just poured my frst trial of 4627 Comfort Blend. SO far so Good. I was wondering if you have to poke relief holes around the wick, and if so, how do you cover them up. I did a search and didn't find anything with regards to CB. I did not put holes in mine as I was unsure how to give a finished look if I did. I hope this is not a silly question! Thank you for your help!
