I have marked the corner to corner lines on the back of two fabrics in pencil. These blocks are 4.5” and when cut and resewn will make a block 3-3/4” square. Not sure of the math on how to make this without squaring it to 3.5” as I just grabbed squares out of the 4.5” squares.

The secret is in where you sew – The fabrics have been marked on the wrong side, in red for you to more easily see which side of the pencil line you put your ¼” seam. It isn’t necessary to mark your stitching line, you can just use your ¼” foot. I wanted make it clearly visible where you will stitch.

Put a light and dark together, and stitch as shown. Cut along the pencil line and press to the dark. Put two together , sew ¼” seam and press. And presto, no bias QST.
