Reticular Origami Sleeve!
This was my final task at the origami course that I attended.
This looks like a spidernet, and it's a bit sophisticated.
After cutting it apart I added space between the lines for the foldings.
I had to make it very exactly to match the corners for each part.
This is the firts step, and how it looks like on the wrong side.
Next step is finished.
Then the whole project is finished, but I have to make the other half of the jacket too! 😅
