One potentially continental desert crossing close to April (5)
I believe the answer is:
quilt
'one potentially continental' is the definition.
(continental quilt)
'desert crossing close to april' is the wordplay.
'desert' becomes 'quit' (I've seen this before).
'crossing' is an insertion indicator.
'close to' says to take the final letters (the close/ending of).
The final letter of 'april' is 'l'.
'quit' enclosing 'l' is 'QUILT'.
(Other definitions for quilt that I've seen before include "Eiderdown" , "Bedcover" , "Bedding item" , "Bedspread" , "continental one?" .)
