"That sounds easy" I thought to myself until I looked at the tutorial link she supplied and realised they were paper pieced!!
This is new technique for me, but once I got going they were quite easy.
Each of the four blocks made were 7" square so when sewn together make a master block of 13".
The fabrics she sent were mainly Park Slope by Erin McMorris, in hues of turquoise/aqua and limey green with some orange thrown for good measure. The only stipulation was that we used the solid white fabric in all 4 sections.
I kept opposing squares the same to give a bit of symmetry, and after lots of rotating settled on the final composition.
