Things that are needed for the engraving, (Things that came from the pack and some things from your house) shown below.
A table would be useful to lean on, preferably one that is steady because you will be there for a while engraving the A4 page. Something to lean the card on (another piece of clear card is in the pack so I am leaning it on that), the card you are engraving, the engraving pen to scratch away the black paint and reveal a beautiful silver pattern. The Things you will need from home is paper to lean your hands on so you do not get finger prints on while working, a damp cloth to wipe away the scrapings from the card while you work, tissue to dry it if still working on the area and some music as you will be there for a while. Keep snacks close by in case you get peckish.
Picture shows that I have started. It is a fun process and interesting to experiment with :)
