Sure you can. You can find some small core molds at Peaks I think. My finished small candle is less than a half pound. If you just dip in clear wax to get use to the way the wax will cut you dont need any color, or just use one color and white. Melt that down and use it for cores and it will be a pastel of that color. Cores can be poured from your scrap wax. If you have lots of scrap the colors will blend together to make brown. The white pigment in the wax makes the brown look like a wood grain in the cores poured from scrap wax. Bruce
