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

'receive knowledge about article of tanner's making?' is the definition.
I can't tell whether this defines the answer.

'receive knowledge about article' is the wordplay.
'receive knowledge' becomes 'learn' (I can't explain this - if you can you should give a lot more credence to this answer).
'about' indicates putting letters inside.
'article' becomes 'the' (the definite article in English).
'learn' placed around 'the' is 'LEATHERN'.

Can you help me to learn more?

(Another definition for leathern that I've seen is " hide".)

I've seen this clue in The Telegraph.
