To make a quarter stitch, bring the needle up at the corner of a square and take it down through the centre, halfway across the diagonal, splitting the aida block. To turn this into a three-quarter stitch, make a half cross stitch across the other diagonal of the square. This creates a half cross stitch across the quarter stitch. If you have to make two fractional stitches back-to-back in the same square, you’ll need to decide which is a quarter stitch and which is a three-quarter stitch. Usually, the threequarter stitch is made in the foreground colour of the design.
