kinda looks like a pattern my grandmother called indian hatchet, with 4 blocks put together to make an x.
She made one out of "cutaways" from a shirt factory. She used striped fabrics for the X's and solids for the triangles. She centered a stripe on the diagonal piece. Even with different width striped fabrics it helped unify the stripes.
She set hers edge to edge, no sashing.
She made hers in the 1960's, but said that it was an old pattern.
