or could these pass for propellers?

Though I have been sewing as long as I’m been knitting, I still don’t feel comfortable with precision patchwork.  Half-square triangles to be specific.  It’s all about sewing on the bias or any angle that could stretch out of kilter.

So I decided to make the windmill block for my grandson’s airplane quilt symbolizing a propeller rather than half-square triangles using this tutorial.  This block still involves an angle but doesn’t have to be spot on with precision points.

Once all the blocks are sewn together, deciding on their placement will be the next challenge.
