3.5 mm hook, and a smaller hook (i.e. 2.5 mm) to weave in ends

Sewing needle

Sewing thread that matches the colour of yarn

2 half-inch buttons

A long sharp tool (I used an awl for bookbinding, but I know that’s not really an everyday handy tool, so I did a quick search for awl alternatives, and the results that came up were metal skewers and long crewel needles)

Sharpie marker

Tape measure

Kitchen scissors
