Patterned fabric is in shreds - the whole lot! (10)

I believe the answer is:

tattersall

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

'patterned fabric' is the definition.
'tattersall' can be an answer for 'fabric' (I've seen this before). I'm unsure of the 'patterned' bit.

'shreds the whole lot' is the wordplay.
'shreds' becomes 'tatters' ('tatter' can be a synonym of 'shred').
'the whole lot' becomes 'all' (I've seen this in another clue).
'tatters'+'all'='TATTERSALL'

'is in' acts as a link.

Can you help me to learn more?

(Another definition for tattersall that I've seen is " fabric".)

I've seen this clue in the Sydney Morning Herald.
