Yes. Each paper fan comes with a white string that is about 4″. In our photos we used regular cotton twine string to extend the length, but any thin string will do (although in our experience fishing string is a bit more difficult to work with). In terms of string color, white/light shades work well against light backgrounds and black string works well against dark backgrounds.
You can attach these to a wall by using any tape. Clear double sided tape will work best. Alternatively, you can attach these to any chair or object by using the included ribbon.
