Celtic Knot Candles

It was one of those 'Eureka' moments.  I actually swung my legs out of bed and suddenly realized that I knew how to make a tartan candle.  But a real tartan candle, not a standard candle with a sticker attached.
It took some time, a matter of months, to make and break and research.  the most difficult part of the process was working out how to make the spine that would hold the whole thing together and then how to get out out of the mold without snapping.
My only problem now is worrying (I'm a natural worrier) that each Tartan candle stays together when in the postal system.
