Sometimes you will find you need a Thomas Hardy paperback, an old tea tin, some military die-cuts, a piece of sari silk printed with elephants, and cat stickers. Maybe you also need some notecards printed with hundred-year-old images of Multnomah Falls.
If you need these things (or a tin wind-up toy or a 1960's beaded sweater or a book of photobooth photographs or some previously-unknown-to-you perfume from Imaginary Authors) there is only one place I know of to go, my favorite store:
There are lots of places I love here, but this place is special, the best-possible version your imagination's dress-up box. I remember the first time I visited, maybe seven or eight years ago. One look & I was done-for (you can watch a video on their website that gives you a tour of the shop, although it is a restless creature & always changing its feathers and colors and finery.)
If you visit Portland, you should wander into this giant jewel-box -- just know you will almost certainly leave with a collection of strange & beautiful clutter.
