Question

Repacking her bag for her trip to New York was a slow process because Sherri's stuff was strewn over every inch of the floor.

Answer 1

Maybe stuff, because we don't really know what it exactly refers to. So maybe replace it with clothes, or something along those lines.

Answer 2

Because of the quality of this description the word to be replaced is stuffed.If repacking a bag for a trip takes time as the person´s belongings are all scattered on the floor , it would be a good idea to mention what it is she has to pack in a less urban language, more appropriate for the tone of the whole sentence.
