Yeah, you just have to keep playing with it. I remember when I started building, it took about a week of constant builds before I was able to get something I was happy with. You have to find the exact thickness of cotton needed and once you get it, you will be able to grab that amount of cotton in 10 seconds. But there has been times where I have re wicked 15 times in a row. So you are not failing at anything, just learning.
One more tip I will pass on is to wash your hands before you roll your wick. All the grease and nasty stuff on your hands gets into the cotton as your roll it and affects the flavor. At least to to me.
Good luck!
