Depends. I generally do better with illustrations than with words. Especially if the illustrations are well done.
Sometimes I get it right on the first try. Other times, my seam ripper and I have a close personal relationship for a while.
I have enough experience now so I can usually tell if the pattern is at fault instead of me. I used to think it was always me that was the problem.
Although it does seem that on something like youtube - the one step or thing I am really "not getting" - is the thing that is skimmed over or not even mentioned!
