I have had another home based business for over 10 years and I agree with LeslieFrost also. You have to constantly keep your name in front of people. And those who say they will call often times never call. A few will surprise you though...have had that happen many times. Or...they will ask you what show you are doing next because they will come and buy more...rarely happens. In fact a lady loved a particular fragrance...I pour candles...and told me to pour her several and she would be at my next show...SHE NEVER SHOWED. Now a guy who loved another fragrance bought all I had at the show and said he would call...he DID call and ordered 10 candles in that scent.
But...I do wish you the best of luck and keep plugging away. Your sign and booth are inviting and would have attracted me to look.
