Pick up basket lying across hotel mat (6,3)
I believe the answer is:
hearth rug
'mat' is the definition.
'pick up basket lying across hotel' is the wordplay.
'pick up' becomes 'hear' (hearing is a kind of picking up).
'basket' becomes 'trug' (I've seen this before).
'lying across' is an insertion indicator.
'hotel' becomes 'h' (phonetic alphabet: alpha, bravo, charlie etc.).
'trug' going around 'h' is 'thrug'.
'hear'+'thrug'='HEARTH-RUG'
(Other definitions for hearth rug that I've seen before include "one's laid out in front of fire" , "Warm floor covering" .)
