First, what not to do:

  Don't display your rug in direct sunlight, as UV rays will fade the vegetable dyes over time. Use UV filters on spotlights or windows.

  Don't hang your rug over a heater or vent, which will cause the fibers to become dry and brittle. Also avoid hanging near humidifiers, which will lead to mildew.

  Don't hang your rug in such a way that it comes in contact with any metal material such as metal brackets, nails, staples, wire, etc. Over time, corrosion of the rug will occur due to moisture in the air coming into contact with the metal.

  Don't allow your rug to come into contact with raw wood, the acidity of which can stain the rug with corrosion. The area of the rug in contact with raw wood or metal should be stitched with unbleached unstarched muslin (available at your local fabric store), or the wood should be sealed with a urethane.

  Never use adhesives to display your rug.

  Don't hang silk rugs or weak rugs that cannot carry their own weight. Use a full-frame mount.

VELCRO MOUNTING:

A popular modern method among collectors and museums is the Velcro mount. Carpets and flat-weaves in good condition can be mounted for wall display using Velcro (fragile, weak rugs or fragments will require full support from frame mounting explained below). Two-inch wide Velcro will support the weight of a large and heavy carpet. If displaying a pile rug, the pile should lay downward toward the floor, if the aesthetic design makes it possible. This also enhances lighting effects, as the angle of the pile in direction of the weave reflects more light than the opposite side. It also allows the warp, which runs the length of the rug and is strongest, rather than the selvage, to take the weight of the rug.

The following Velcro mounting procedure should be repeated approximately every 2 feet vertically down a large, heavy rug, to provide more evenly distributed support. Or, it can be repeated along the sides and bottom of the rug.

1. Purchase 2-inch wide Velcro by the yard at your fabric store, the length of your rug.
2. Purchase unbleached muslin at your fabric store and cut and hem it on both sides so it is approximately 1/2 inch wider and longer than your Velcro (muslin protects your rug from being stained by metal screws, staples, and raw wood).
3. Sew the fuzzy side of the Velcro to the middle of the hemmed muslin strip.
4. Sew the muslin strip along both edges to the top of the rug, using a whipstitch, preferably with cotton or linen carpet thread that matches the color of the rug.
5. Staple gun the hooked side of the Velcro along both edges of the Velcro to a flat piece of wood. The wood should span the length of the rug and be 1/2 inch wider and longer than the 2-inch Velcro. If the wood is untreated, ensure it does not come in contact with the rug and only comes in contact with the muslin.
6. Mount the wood on the wall with screws (you may need a drill, electric screwdriver, stud-finder, and dry-wall screws, depending on your wall).
7. Press your rug firmly against it. The size of the 2-inch Velcro allows room for adjustments in hanging the rug straight.

FRAME MOUNTING:

Construct a frame the size of the rug. Materials for making a frame can be found at your hardware store or art supply store. Stretch unbleached muslin over the frame and staple it to the back. Stitch the rug to the muslin using cotton or linen thread that matches the rug. Use whipstitches with 1/2 inch spacing along the edges of the rug. Make one stitch approximately every 1 to 2 feet vertically across open areas in the middle of the rug, to provide additional support.
