Back before it was a "movement" I had issues with the more modern quilts that started cropping up. It wasn't because they weren't traditional or because they were different - it was because the construction on the quilts was ... wrong, I guess? Poorly constructed would be a better way to put it maybe. And I'm really very sorry if it offends anyone here, but I don't see where taking a bunch of jelly roll strips and sewing them together is any great feat. I do have a lot of respect for the quilts that at least LOOK like there was some design plan for them, but the ones that just look thrown together escape me.
That said, I wouldn't call the quilting I do "traditional" in a traditional sense. I would agree with whomever called it contemporary - I like traditional patterns done in more contemporary fabrics. If I had stuck with traditional patterns made from reproduction fabrics (30's, Civil War, etc) I would have stopped quilting long ago. I HAVE done more traditional work ... but I prefer a more contemporary look through fabric selection. I've also never really been a fan of "scrappy" quilts though I've done a couple myself - I call them controlled scrappy quilts.
All in all, I think that if the construction of a quilt is durable, that's all that really matters. There's no reason we all have to agree on whether or not a particular "movement" is legitimate or not, and I think that the resurgence that's happening as a result of the modern quilters will only increase the fabrics, threads and tools available to all of us. In fact, I think the recent resurgence of sewing in general can only be a good thing for all of us.
