Here’s the trick: use fusible interfacing to hold the quilt squares in place before you sew them together.
Arrange the squares on the fusible side of the interfacing, press them in place, then sew the seams. Since the squares are already secured, they’re much less likely to shift while you sew, which makes matching those corners a lot easier.
I have a detailed step-by-step tutorial for this method — check the first comment for the link.
