If its coming up that short I suspect cutting errors. Are you starching and pressing your fabric? How are you making your HST’s? When cutting fabric is the ruler on the fabric?
It looks like each unit should be 3.5 before sewing together, is each unit measuring up to the correct size before sewing the units together? Are you squaring up each unit before sewing them together?
