The main problem is when I cut my squares to 8/12 in., then sew my squares, then match seams this is where the problelm begins. After matching seams after turning right side out; the square seems to have a slight twist in it . Then if I fold corners to the center my 4 tips will not always be quite right.
I have even cut out 1 square at a time to make sure that my measurements are correct.
What could I possibly be doing wrong?
