First I painted my nails using the colours provided in the set and let them dry. I then added a top coat, and carefully applied the trimmed feather peices while it was still wet.
Once the feathers are on your nails they need to be trimmed down as closely as possible to the nail, and then filed for extra precision. The final step is to add a top coat again to seal the feathers in place. I'm in two minds about whether they actually looked better before the top coat, as I think the colours where a bit more vibrant when dry. I've included final pictures below, and above that what they looked like pre trim and top coat.
