Thank you for your feedback!
Landry & Arcari - they have stores in Boston, Salem and Framingham.
Here is their ANIMAL PRINT selection: www.landryandarcari.com/GalleryOverview.php?f=Animal-Print-Carpets
and as noted elsewhere on their site,
“ . . . almost any broadloom carpet can be cut and bound to form a hall or stair runner.”
Good luck with your project!
