When applying the decal, be careful as the Rothko ones are very thin, so they can tear easily. When theyre on the headstock, they may look a bit wrinkly, but thst disappears as the water evaporates.
To seal the decal in place, apply very light mist coats over it once its dried out. If you apply too much lacquer / finish, the decal will wrinkle up again.
be careful, and take your time, and you'll end up with a fantastic lookjng headstock mate.
