Some images that are under shibari that do not involve ropes: post #373888 (ribbon), post #91032 (vine), post #443680 (tape measure), post #604678 (swimsuit strap), post #1014650 (chain).
This was also under shibari, but wasn't sure if these should be under the tag post #134369 (leather strap outfit) and post #107539 (Christmas lights).
