This is a very interesting discussion to me as I work on developing my new full time fabric arts business. As far as copying my work from my photos...I think my particular type of quilting would be difficult to do that way, though perhaps not impossible, though I think I would even have a hard time reproducing exact or even near copies of my own work like my knight quilt, for instance. I do see some fabulous and beautiful quilts, however, that nevertheless could be copied from good photos if one were skilled in the techniques (rather like "good" forgers of paintings can copy them to the point it takes an expert to tell the difference). But if the quilter is so skilled, why copy someone else's?!!!
In the future, though, I am planning to develop some quilts with patterns and even printable digitized items and in-the-hoop applique/embroidery to go with the patterns. That might be a little less difficult to copy from pictures. It's a good thing to think about in advance of this.
I still rather think I'll share my struggles with crafting my art quilts with photos. One of the things I want to do, with my website and blog is develop interest in my quilts as art--perhaps for eventual sale--and in my techniques to share with others.
I really agree that it is a shame we have to be so careful about this. It's a lot more fun to share and I love to see other people's work too here at home in front of my computer with my shoes off.
To me, it doesn't spoil it to see it on the Internet or in a magazine if I at last see it in person. There's so much more to see in person.
