In the past I got the idea to stitch a version of the periodic table.
After a lot of thinking I decided it should contain the following information:
The latin names
The short version of the names
Overview of the eletrons and ther placement
numer
lack of stabile isotopes (radioaktivity)
along with a speciality stitch for each element

The next thing I did was to design a basic layout for the elements

Thereafter the overview of the entire table (on two A4 sheets)
