One question I am often asked is why a Japanese hanging scroll (Kakejiku) does not hang completely flat. This can be particularly noticeable with newly mounted scrolls or those that have been kept rolled up for a long time.
There are several possible reasons:
- A scroll naturally retains some curling from being rolled for storage.
- The layers of paper and silk in the mounting may be relatively stiff.
- Changes in humidity can cause the materials to expand or contract unevenly.
A slight curl may gradually lessen after a scroll has been hanging for a while in a stable indoor environment. However, not every scroll will become perfectly flat.
Some people gently roll a scroll in the opposite direction to reduce its curling. Although this method is sometimes used, it requires care. I would not recommend trying it on an antique or fragile scroll without advice from an experienced professional.
If there are deep creases, loose or flaking paint, or pronounced warping, it is best to consult a scroll mounter or conservator rather than trying to force the scroll flat.
