my 2 cents worth...there is nothing new under the sun...when we draw. sew, build etc. there is usually some where someone who has done something pretty close to the same..copying something to defraud ..best not to do it! This may be the intention of the law..
I make my own designs...lots of times I find someone else has come up with the same. maybe different technique. or some other interesting twist..but..all of us get our ideas from copying something..Discovery of "new" things and how to do them is what makes life worth while in my book..yet each one of us have a unique gift that I find fascinating. Some one has said a good teacher is one who releases the student to go beyond that which is taught to find a more excellent way.
Be all you can be and never stop..jump over the obstacles..help each other..
don't fight on the way!!
maybe some old indian said this! I know this old granny did! Happy sewing!!
