I've been lurking around here for quiet awhile now, getting tons of helpful info from you all. I'm making candles for myself, but am wanting to make some for my family. I'm making 8oz. jar candles, but am having the wick "mushroom" on me after burning for awhile. I've tried different wicks, but am wondering does the "mushrooming" wick mean that it's too big for the jar? I would appreciate any help on this Thanks!
