The Ninja guild provides a number of ways to wrap gifts. There are wrapping papers and furoshiki cloths to be dyed, or various gift boxes to be decorated by yourself. Writing paper and wallpaper may also be dyed.
Cloths, papers, and marbling combs are available from Iki Banu. She even sells trays for dyeing now, so non-assassins may benefit from the craft.
First you will need to fill the tray with water. The tray holds two cups, or one pint. You may use a bottle, pot, bowl, etc. to fill the tray.

It takes a highly trained, dextrous hand and an eye for beauty to tie the intricate knots with the cloth. Wrapping paper, however, appears to be straightforward and doesn't require a skillcheck.
