I do stringing so for me this may be a little different...
If it is a new technique ( how to string and come back through etc ) that I am not familiar with since I am fairly new, I may follow the pattern technique exact but use whatever beads I prefer whether it would be color size etc. So like the others have stated it looks completely different.
Usually I will take an idea and do my own thing as well. I also will look at pictures and find inspiration, sometimes from a specific technique within the instructions.
I like the idea of a simple/basic pattern with additional difficulty levels. Perhaps a basic with inserts for medium or difficult. I like that idea and would subscribe. I think we all have a tendency to learn from everything, even if it is not in our specific area, or we can find a color combination etc that could be a inspiration.
One magazine with give instructions and have the base price ( under $10 ) then they will have inserts with more expensive options with prices for that. I like that as we all have different budgets or access. Sometimes I cannot find the beads they use even if I wanted to but can find something in one of the other options. So I end up mixing things up.
Just my thoughts...
