Hi Dave, Thanks for the response, but I was actually referring to the crimps folks use on gel candle wicks to prevent the flame from reaching the sand or whatever the base may be and now after re-reading my message, probably should have said metal jewelry beads instead of crimps. I bought my wicks already pre-made but am just tyring to figure out what size bead to put on them to stop the flame. I'm gonna guess here and say I should probably take a wick with me to Michaels and measure it that way? Thanks again! Chris
