Being a Computer Aided Draughtsperson (CAD Operator) by day, I draw the whole quilt from which I designed the blocks with Sierra Embroidery Software.
As the rules stated that square or rectangular shapes was not permitted, I settled on a diamond shape.
By now, it was already mid March and as D-day is the 1st of May, I concentrated on getting it finished in time.
And this is the end result.
The pattern is available here.
