Place 4 (four) needles through the holes in the top
There's an extra needle in the handle. Spin the cap back on.
Ready to use.
If a needle breaks - replace it.
Easy as that. The handle comes with 5 - 36 gauge needles. You can replace these needles with any gauge you choose... Just be sure to replace all the needles with the same gauge or length. Happy happy felting!
