I am new at this and i have run into a problem..my black is sticking together once i get them into a package...The things i am thinking is maybe i used to much colorant or not enough worm oil......This is happening in the black colors and slab slay'r are really bad for sticking.....So i guess my question is how much worm oil do i need to use in packages of 20. Or do you think something else maybe cause this problem........
