Begin by drawing a chair that fills up the whole page. A real chair or an imaginary one. A sketch is fine. As long as the chair is as big as the page.
Your drawing divides the page into sections somehow.
In each section, write something about a chair.
A chair you have known. One you have forgotten. The best (and worst) qualities of chairs. A chair that isn’t a chair at all.
When all the sections are filled and additional decoration is complete, give your work a title. Write the date on it, too.
