Sylvia Townsend Warner to George Plank, 1961
"You have the nicest hand with a parcel. I can't think of anyone to match you in parcelling except perhaps Henry Tilney, to whom I attribute all the graces. Mr. Knightley's parcel's would never come undone, true; but think of all the paper and string involved. Elinor had to do up all Edward's: Edward required a great deal of buttoning and unbuttoning; though she enjoyed his dependence on her: the butler did all Marianne's & Colonel Brandon's. Mr. Darcy did exactly three parcels a year, for Lizzy's birthday, for New Year's day, & for their wedding anniversary. The product was excellent, but he took hours to achieve it. And locked the library door.
(The Letters of Sylvia Townsend Warner, London, 1982)
It's a pity she didn't say anything about Captain Wentworth and Edmund Bertram, but I think I can fill in those holes: the dear Captain was too busy at sea, and never sent any parcels, and Edmund never had any practice, because Aunt Norris always made Fanny do it before he had a chance.
And yes, Henry Tilney would have the nicest hand with a parcel, but I'd be careful if I got one from him, because I'd always expect the memoirs of the wretched Matilda to fall out as soon as I opened it!
