Pictures should be hung with low stretch polyester picture frame hanging cord. Cheaper picture cord may be made from nylon, which can stretch by 14% more than polyester cord. Picture cord can be stronger than wire and is very commonly used by many picture framers. You should choose the combination of picture cord and picture hanging hardware like d-rings carefully to ensure the picture frame is held securely on the wall. We have several different thicknesses of low stretch cord available (#1, #2, #3, #4, #5) and can be bought per metre or larger sized rolls and spools. We also stock brown picture cord.
