I have to agree totally with Sharon. I have never smelled such a strong Lilac and it is one of my best sellers. Have you tried putting the max scent load in your candles?
Screw the screws!!!! I use to use them all of the time and absolutely hated them. Just run to WalMart and get some HVAC Tape, it is silver in color and is by the Duct Tape. This tape will hold up to the heat and you will never have a leak.
I think they look really good. I have never tried to sell one that looks like that but I am sure that there would be someone out there that would like it.
Peak carries a white pigment block that you can add to the wax. It is really not a very good thing for wicked candles (can clog the wick) but works well in a cane. Worth a try!!!
