Disclaimer: The following is my opinion and may or may not reflect legal guidelines:
There has been quite a bit of talk lately on FaceBook about copying artist work and about competing among artists and "want-to-be" artists. Copying to learn a technique is what goes on in a class. It has been a tradition amongst artists for centuries. Visit any large museum and you are likely to come across a class copying the masters in order to learn to see and to do. It is one way to learn.
The project you do in some workshops is definitely the design of the instructor. To copy this design and sell it as your own is wrong. To teach the exact class is also wrong. The right thing to do is to use what you learn as a springboard for your own original work. To do otherwise is, I believe, plagiarism and puts you in competition with the very person who was kind enough to share ideas with you. If you have taught classes yourself, you know that there is a great deal of thought, creativity, planning and trial and error that goes into the creation of a class. If you have created an art piece, you know how difficult it is to come up with something original. It takes knowledge, skill, imagination, hard work, time and material. If the original artist sells his/her work and you sell your copy, you are belittling and cutting into the profit of the artist who perhaps makes their living with their art. This is how I feel about it. I would love to hear your thoughts on this.
Speaking of competition, my peonies in my yard are competing for space. The flower heads are easily 10" across when they are open. Peonies are so beautiful.
We have been collecting vintage cameras and we have a bunch of them for you in the store. We have both box cameras and bellows cameras. Come have a look.
