제 경우는 위 사이트를 찾기 전, 아래의 간단한 팁을 보고서 시작해 보았습니다.

Subject: Re: Help with crease patterns!










Crease Patterns can be a challenge, particularly if you don't have a lot of experience with origami yet.




Here is how I learned.




First I folded a lot of fairly simple models such as the traditional crane and traditional frog and looked at their crease patterns until I had a good


feeling for the patterns that the various pieces of the model form on the paper. I did the same thing with some more complex models as well. The


idea is to become familiar with the patterns various known models make.




One important thing to remember with a crease pattern is that it is not complete. The pattern only shows you the creases needed to create the


base. It does not show creases for details, nor does it show creases that do not directly contribute to the base (creases made as a side effect of


the folding process) It is up to you to deduce the detail work. For example, a crease pattern for the traditional crane would only show what


you the creases for the bird base.




Unfortunately many people do not indicate on their patterns what folds are valley and what folds are mountain so you probably have a 50/50 chance of


getting the color on the right side (you get a better feel for it with experience). Just pick a major crease and choose a direction. All the


other crease's directions will be determined from your first one.




To fold a crease pattern, all I can recommend is to start creasing the paper. Your experience and some common sense should guide you on what


direction the creases should go, but as a general rule they alternate between valley and mountain. Once you made all the creases, it should be


obvious if you made a mistake on the direction of a fold as the paper will resist collapsing into the base. Once the creases are made, the paper will


naturally want to collapse (some models do not naturally collapse into a base so be wary) and you will have your base.




Now look at the picture that comes with the crease pattern (a complete crease pattern will come with a photo of the finished model). You should


be able to see what points of the base turn into what parts of the model and what you need to do to get the points into the correct position and


size. If you can't tell, you may have collapsed the paper incorrectly so try reopening it and seeing if there is another way to collapse it.




With experience one can tell just by looking at a pattern what parts of the pattern turn into what part of the model.




Crease patterns are much more difficult to work with then diagrams. You will go through a lot of trial an error until you figure out what you need


to do. Be patient and keep at it and eventually you will figure it out.
