If you have ever had the experience of seeing a really old document, you may notice that the edges look kind of ragged. This is what is called a deckled edge. It is called that because the uneven edge of the paper is formed by the part of the paper mould called the deckle, which is the frame like structure in the photo above.
In my post on making the book Bedtime Story, I had mentioned using a beautiful handmade paper I purchase several years ago. The paper measures approximately 6″ x 8″ but I also needed a few pieces that were about 3″ x 6″. If I were to get out scissors or an Exacto knife, I could easily make a smaller piece of paper but it would like sort of odd with three deckled edges and one straight edge. So how do you go about getting a false decked edge? It is pretty simple but first a bit about paper.
The piece pictured above is western handmade paper. What that means is that the paper has very short fibers. If is also a relatively weak paper compared to Eastern style papers (often misnamed ‘rice’ paper) that are long fiber papers. So the technique I am about to describe works best with western style papers because the short fibers break apart easily when wet.
After measuring where you want the edge to be, you take a soft brush soaked with water and brush it along the ruler edge. If the paper is very thick (which was the case with this paper) you need to do this several times until the water soaks through. Then you pick up the paper and very slowly and carefully start to tear from top to bottom. The result is a false deckle that should serve your purpose.
