Paper that size can expand >considerably with changes in humidity. Although 19th century pasteboard could be made by laminating sheets of paper to board, these were generally small scale. Traditionally, large sheets of watercolour paper would be pasted onto linen or stout paper and tacked around a wooden stretcher or strainer. Modern conservation alternatives include wrapping the paper around an acid free honey comb core board, attaching it at the back with either starch paste or pre-prepared acid-free tapes. Japanese paper margins or linings can be used to pre-stretch the paper and/or provide an additional barrier layer. This eliminates the dangers of movement, curling etc and is easily reversible as no glue is used on the object itself.
