The ends of the wire will be kept flat so you can hang on the wall with small nails or small clear command hooks (not included but you can buy online or in most hardware shops for a few pounds). Or you can lean the words on a shelf.
The ends of the wire will be made into prongs, roughly 1 inch in length. With this option you will need to drill small holes into the wall to slot the ends into. Hold the piece against the wall and using a pencil mark where the prongs meet the wall. Drill holes using a 3mm drill bit and slot the prongs into the holes – it’s as easy as that!
