Alternating the orientation of half-rectangle triangles adds some interesting movement.
In the spirit of transparency, and giving credit to inspiration, I had a look around my Pinterest feed to see what other quilts are similar to this design. I see a resemblance to the Colour Explosion quilt from Bonjour Quilts, the Modern X quilt from Christa Watson, and the Mesa Mini Quilt from Michael Ann Made, among others.
I didn’t derive my pattern from anything else, but it may have been inadvertently inspired by others’ work. Who can tell what ideas floating around my head inform each sketch?
