I would definitely recommend The Stitching Post in Sisters, Or. I was lucky enough to go to the Sisters Outdoor Quilt show two years ago which is quite famous. The little town was packed full of people but it was a beautiful quilt show in a beautiful setting. I'd love to go back to the town sometime and be able to better explore the quilt shop and other shops and galleries when it isn't so crowded. We travelled from Nebraska specifically for the show and loved our whole visit in Oregon.
