I went to the recent Paducah show and purchased a book with pics of all of the quilts in it to enjoy for later. The quilts that I really like I may take a pic especially one of the close up detail if permitted to enjoy later. If you can purchase a booklet from the quilt show that may be the way to go.
At the National Quilt Museum they may have postcards of the quilts that you can purchase and I do believe they may also sell some sort of booklet of the quilt displays.
There is one Japanese woman (Emiko Toda Loeb) who makes these wonderful detailed double sided quilts that were on display last year at the museum. I noted her name and searched for her book on google only to find that the book is not for sale in the US. I did not purchase anything in the shop because I thought I could get her book. Was I disappointed.
