Which needle sewing machine?

Have you ever? you word, place the amchine and after some time when the reume for a new job, do not remember more wich you mounted needle, how to do it?

I adopted this method, I leave a piece of fabric under the presser foot so I have the certinty of knowing that the needle is mounted to sew that fabric, pictured, the mesh.......

If we need to change it and put it away? do not worry, use the same fabricunder the presser foot and this riddle now gets.
