Hi I have been making tarts for quite awhile now. I use the EcoSoya piller wax. As for scents I use alot of scents from Peaks,Solas and Just Scent. Everyone on this board has there own ideas on who has the best scents. So you will just have to order some samples and see which ones you like best and which ones work well in your wax. When I make my tarts I weight out a pound of wax heat to about 150 155 degrees. Add my color stur like mad and then add my scent and sturr like mad again. When I'm done mixing I pour into my molds and let dry. Tarts were very easy for me to make. And they are a big seller in my store. This week alone I must have sold at least 100 packs of them. There is alot of trial and error in candlemaking. You will just have to test test test. Regina santa chee
