Thanks to all for your advices, the past evening at home I made some test and calculation. I came up with 8 molds I can fill at the same time. The amount of wax is about 900 grams, the average cost per candle (excluding colors and FOs that are very small quantity) is 0,50 - 0,60 euros including trasparent little bags (I can buy 100 bags at 6 euros). This morning I will call this lady, if she agree paying 1,50 each I'll accept the order. It is a lot of work, but I intend to do it, hoping not to fall sick and having to stop pouring!!! For labels I don't know what we will do, she doesn't mind if her shop's name is on the label or not. Call me stupid, but I think it is an opportunity. Kisses
