I have a tapestry on my wall. It is meant to be hung, unlike a carpet, which can be hung or put on a floor. It is hanging with Velcro. One strip of the Velcro is on the back of the tapestry. The other is on a 1x3 board so the the tapestry is supported along its length. It is the long edge of the tapestry which is supported, unlike rugs which are usually supported by the narrow end. The top edge of the board has eye hooks, which then slips onto another set of hooks on the wall. I didn't come up with this myself. The artist who made the tapestry prepared it and sold it with this hanging system in place. I don't know whether putting a Velcro strip on the back of a silk Persian would be the thing to do. I would want to check with a store which sells them, or even an antique dealer. I like Alberts's idea with the tack strip. The more tacks the better so that each holds less weight.
