Beautiful work! I'm jealous of all those neat stitch types.
There's a bunch of us young'uns hanging around, but we're few and far between. I'm 29 and I still get the odd look from other patrons at the LQS. Thankfully the employees know me by now!
However, there is such a thing as Modern Quilting and that's what the survey is referring to. I'm still new to the quilting world, but modern quilting is quite different visually than traditional quilting and appeals to a much younger set of seamstresses!
