Testing/Sampling
I know that "testing" before continuing is a good idea.
Examples: markers, glues, fusibles, threads, washing techniques, etc.
I also know that making a test block is a good idea before continuing. The pattern is not always right - or my understanding of the construction is fuzzy.
I also know that more often than not, I am impatient and just go ahead and try something and hope that it works out okay.
How about you?
