I'd get an assorted packet of sewing needles, a small pair of scissors, an assortment of small sewing thread in black, white, and an indeterminate - say grey or beige, and a few extra shirt buttons. A little packet of bondaweb might be useful as well for mending holes. Put these all together in a tin or small tupperware box.
Housewife's / hussifs would be in a tin or kept in a linen roll traditionally and might have included a darning mushroom, but we don't darn socks or woollies any more.
