I too went to the NH show, Quilters Gathering, but I loved it. So many gorgeous quilts, enough in the do-able range (or at least some aspect was do-able). I've been to some shows where most of the quilts seem to be made by professional artists, so far out of my range.
Actually I was grateful not to be tempted by vendors selling specialty items that never perform as well as expected. I only bought three items: superior monofilament thread, 505 spray, and one purse pattern. Proud of myself for not going overboard.
