Having a pattern of dots (8)
I believe the answer is:
stippled
'having a pattern of dots' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for stippled that I've seen before include "Marked with dots or specks" , "Dotted, speckled" , "Having a mottled effect" , "Having a pattern of dots, on a ceiling perhaps" , "Painted in dabs or dots" .)
