Ford Fiesta, perhaps, in shade (10)

I believe the answer is:

crosshatch

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

'shade' is the definition.
(I know that crosshatch is a more specific form of the action shade)

'ford fiesta perhaps' is the wordplay.
'ford' becomes 'cross' (I've seen this before).
'fiesta perhaps' becomes 'hatch' (I can't justify this - if you can you should believe this answer much more).
'cross'+'hatch'='CROSSHATCH'

'in' acts as a link.

Can you help me to learn more?

(Another definition for crosshatch that I've seen is " Scotch rash (anag) - shade in a drawing".)

I've seen this clue in The Independent.
