Wet mounted blank wall scrolls are created using traditional Chinese scroll making techniques, they are more expensive and take much longer to create than modern wall scrolls. Though modern wall scrolls have more finished look, wet mounted traditional Chinese wall scrolls have their own advantages.
If you want to go with a traditional Chinese wall scroll your patience will be rewarded, the scrolls will get smoother the longer they are hanging as the weight of the scroll rod will eventually cause the paper to become straighter and smoother. The other reward is longevity, no one is absolutely sure how long scrolls will last when made using modern techniques, and results may vary according to the skill of the artisan and the quality of the materials used. However, scrolls made using the wet mounting process will last many lifetimes, and should they need repaired or replaced the painting can be remounted.
