I just received my order from Peaks:yay: and I ordered the sample pack of cotton core wicks. On the packages they range from C-30 thru C-80. I need help cause all the research I've done I haven't seen these particular numbers referenced, So I dont know where to start with wicking what size jars. I am working with 100 soy and in 6 oz tins and pint jars. Can anyone please help.
