'interior decoration' is the definition.
'tapestry' can be an answer for 'decoration' (tapestry is a kind of decoration). I am not certain of the 'interior' bit.

'pretty as can be' is the wordplay.
'can be' is an anagram indicator.
'pretty'+'as'='prettyas'
'prettyas' is an anagram of 'TAPESTRY'.

Can you help me to learn more?
