I don't know the pattern, but I see some of the blocks not lining up the way I "think" they would be … top row first three blocks looks fine, but then the fourth block has red on red … I would turn the fourth block so that it has the white border touching the red border of the third block.
Same thing with fourth row down - the last block - I would turn it so that the red border is touching the white of the adjoining block.
Otherwise, it is a stunning quilt!
