Summer is one of three palettes of 25 Kona Solids colors that I curated for Robert Kaufman in connection with the release of my third book, Patchwork City, in 2014. The packaged fat quarter bundles are no longer available, but you can refer to the chart below to assemble the same Kona Solids colors.
The Summer palette can be used to make this version of my Aviatrix Medallion quilt (pattern linked below) using this guide.
This is also a great palette for making my Preppy the Whale quilt (pattern linked below).
