What about a class that you take and you are given a photocopy of a pattern that the class is making. Is the author of the pattern getting the credit or do we need to ask the teacher if this pattern is copywrited? I am confused. Also, if I make a quilt block from a pattern and post a picture of the quilt I made from this block and someone wants me to do a tutorial, am I breaking the law by doing a tute? I am sure that the person who did a tute on the folded dahlia did not design the pattern (or maybe they did LOL).
