Kona and Kona Bay are not the same brand. Kona Bay has to (or had to if they are now out of business) add the word, "Bay" to make it not be a trademark infringement. They had to use the whole phrase, "Kona Bay" on all their fabric products. You can call your coffee, Kona Coffee, you can call your pineapple, Kona Pineapple, but you cannot call your fabric Kona. It is a trademark of Robert Kaufman and only he can use it.
