our thrift shops rarely have any fabric--even sheets. About all there is are poly curtains. Our guild has an annual sale and I sometimes find something I can't live without (like when I scored a big bag of 5" sq. of juvenile fabric for I Spy quilts!). I've been trying to dip into my stash more and more.
I've also noticed that both my quilting customers and what I'm seeing at shows are smaller quilts--lap and wall hangings. i think that will likely continue as more and more quilters purchase sit-down and mid-arm machines and also start using rulers like Westerlee on their domestic machines.
