Living in Pennsylvania, it's commonplace to see Amish just about every day you go shopping. I used to work at Joann Fabric and the ladies were always in there getting fabric. Yes, they were getting prints. And yes, they were wearing prints. Same thing in Walmart and grocery stores.
Most drive plain black trucks or vans. Of course you still run into some buggies every now and then. As for them not wanting to get their picture taken, they must have forgotten to tell all the ones around here because I see them in the newspaper and on tv all the time. (right now they are seling fireplaces that they made. Very nice, actually)
But it's not just quilts. It's the same thing with the hand made furniture. You see it at craft shows. There will be duplicate things, one made by amish, one not. Guess which ones sell firsst at a higher price?
