The contrast between your advice to aristo and mine inevitably led me to this passage from Philip Pullman's "Book of dust", which I came across only yesterday!
"Those parcels. How d'you make 'em so neat?"
"Neatly, Malcolm"
...
"I thought neat was all right" he said.
"It depends on whether you want the idea of neatness to modify the act of tying the parcel, or to refer to the parcel itself once tied"
