Just an FYI , I went to the Kaufman web site a did a bit of a search there are several distictly different fabrics that all carry Kona as part of the name . Kona is a registered trade mark of Robert Kaufman. There are 11 listings for fabrics that have Kona as part of the name.
If you go to the web site , link below , and click on the select a collection menu , scroll down to Kona you will see all the fabrics that are part of what is known as "Kona". As a consumer you need to know which one ( the specfic Kona line, not just color) you like so you can find the same one again. Read more of the bolt than just "Kona".
