I did 4-rd granny squares, turning after each round, and joined them as I went. For the border I did a round of SC grannies and then a round of regular SC.
For the yarn, I used Turqua, Shaded Dusk, Light Blue, Real Teal, Royal, and Macaw, all in Red Heart. Clear Blue in Loops & Threads Impeccable. Silver Blue and Dusty Blue in Vanna’s Choice. Aqua in Bernat Super Value. And Midnight Blue in Caron Perfect Match.
