I'm a little stuck... Click here to teach me more about this clue!

'crafty instruction' is the definition.
The definition suggests a singular noun which matches the answer.

'sort lanes out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'sort'+'lanes'='sortlanes'
'sortlanes' with letters rearranged gives 'ART LESSON'.

'for' acts as a link.

Can you help me to learn more?

(Another definition for art lesson that I've seen is " Painting study".)
