I made some palm votives for Christmas gifts. I usually use soy votives and can wick them no problem. But these palm ones are giving me a headache. They seem to burn fine with a CD8 for a while, then they kind of crater and the flame is just marginal, not super small but not really doing much either. Any suggestions? The local supplier hear carries CDN, RRD, some Cottons. Any others I'd have to ship in and that would take a while. BTW, I tried zinc too, the flame went out. santa chee
