cut small strips of net big enough to cover your nails, leaving a little extra overlapping (you can neaten them off later).
Then paint your nails with one layer of base colour. Don't leave the nails to dry for too long before sticking the netting on as the base colour helps the netting to stick.
Simply allow gentle pressure and press the netting over the top, then leave them to dry for a few minutes. Now you can cut neatly around the netting to neaten them.
Apply a few layers of clear polish to keep the netting in place. There you have it netted nails :)
