I spotted this attractive Shahsavan Khorjin on www.Cloudband.com offered by a dealer on our Trusted resource List, Aaron Nejad of London.
Trusted Resource List - Rug & Carpet Dealers Outside The U.S. Aaron Nejad Antique Carpets.
Here we can see the slits for loop and slit closures. The front panel has the slits and the loops are fastened to the back and extend through the slits.
This guard border is used in a number of places including Khamseh and Hashtrud Miyaneh but with this main border I attribute this bag to Moghan Savalan. See SUMAK BAGS OF NORTHWEST PERSIA AND TRANSCAUCASIA, plate 91.
