For instance, pottery vessel displayed by husband and I (10)
I believe the answer is:
handicraft
'for instance pottery' is the definition.
(pottery is a craft)
'vessel displayed by husband and i' is the wordplay.
'vessel' becomes 'craft' (synonyms).
'displayed by' means one lot of letters go next to another.
'husband' becomes 'h'.
'h'+'and'+'i'='handi'
'craft' after 'handi' is 'HANDICRAFT'.
(Other definitions for handicraft that I've seen before include "sewer's output perhaps" , "manual skill" .)
