Good question. I find myself attracted to "modern" fabrics. I like the openness of the designs and am always attracted to large scale prints (just check out my stash - I never have enough blenders). It looks great in angular quilts with lots of background to separate it from other fabric, but the fabric doesn't seem to fit well in more traditional settings.
I like modern quilts but will never make only that type. So while I am always drawn to them in LQS, I usually don't purchase because I can't quite figure out how it will fit in the quilts I make. I'm sure I will keep trying though.
