The Thomas Jefferson Building of the Library of Congress is a monument to knowledge. The whole building exudes the value of knowledge. As well, it is a gorgeous building, with every surface covered in some kind of artwork celebrating knowledge, books or libraries. I took dozens of pictures of floors, some of which I may drag out later for your enjoyment. Here are a few to inspired you to greater borders and medallions for your quilts.
I love the common designs that mosaic art (and other arts) have in common with quiltmaking.
