Tips
history
From Ouyang Xiu's 《试笔》 (Song dynasty), quoting Su Zimei: 明窗净几，笔砚纸墨皆极精良，亦自是人生一乐。 - 'Bright windows, clean desk, fine brush, ink, paper - this too is one of life's joys.'
memory
几 here is jī (low table / desk), not jǐ (how many). Picture a sun-lit window over an immaculate writing desk - the picture is the meaning.
