Every time you buy a pipe, you curate and shape your collection. Some do this deliberately, emphasizing certain brands, shapes, materials, artisans, sizes, etc. Others of us go for what we like and create our pipe stable before we exactly conceive what it will be. I have six or eight higher end pipes I treasure, but I think my racks have been "designed" by more traditional shapes and materials, with the definite target of attaining a first rate smoking experience at distinctly moderate prices. Rather than feeling cheap-o or bargain basement, this has become good sport. How do you shape your collection, or how does your collection shape itself?
