No pattern followed. Made a giant rectangle in hdc with the brown. When I used almost all of my 4 balls of Cascade 220 in that color, I closed the sides with sc in the contrasting color and made the straps to help keep it closed. Made up the hoops and put the rings in for the strap before felting and this is the end result.
Used almost 4 balls of 220 in brown bear (maybe 10 feet left), and only 1/3 of one ball in the sand.
