Pre-creased equilateral triangles grid

Hi!

I'm wondering if there is a method of folding an equilateral triangular grid that makes the folding more accurat than other methods? If it's better to do the divinding of the paper on one side, or to start with a certain corner of the paper, or certain landmarks that minimize the risk of losing the accuracy while folding? What are your experiences?

Making a precise grid of folds it is really not easy.
Except from the method you will use, the final precision will be strictly related to the precision of the first element you will fold (in you case an equilateral triangle)

So I suggest you to be as more precise as you can on the first molecula, and then to refer to it all the further folds.

When I have to do a shape involving 30° or 60° angles I use the following technique. With just two folds I get my target. More, the less fold you do the less error you add to your design.

Hi Anine,

I use the method shown here in Eric Gjerde's Tessellation Basics Booklet...you can download it HERE

Enjoy!

Since the purpose of these grids are usually tessellations, folding from hexagons is a method used by many. An accurately cut hexagon allows for an accurate grid when aligned to the sides of the hexagon. There is an alternative orientation for the grid that in some cases leaves less unused paper on the edges that I showed on this thread
