You need to describe every stage in order, using sequencing language and mostly passive verbs.
How to practise Count the stages and note where the process begins and ends. In the overview, say how many stages there are and whether it is linear or a cycle. Use sequencers: first, subsequently, once this has happened, finally. Turn labels into full sentences with passives: the clay is dug up, then it is shaped.
