I finally had reeds so I need to prepare them for making my first reed octahedron.
My next step was to cut the reeds identical in length, which didn't seem such a hard job, but I was wrong. I had read that reeds can break in the process of cutting, but I wasn't quite ready that it would be so difficult to cut them in equal pieces. I tried out all knives and scissors I had, but making them perfect without a single breaking was a mission. If the straw is broken the thread may break it even more as it holds the structure.
After a slow process of sowing I had finally made it.
