square the block from step 3 leaving a 1/4" seam allowance from the points then find the center of the long side of the large triangle and pin the center to the center of the side you'll be sewing it to.. trim the finished block leaving a generous 1/4" seam allowance after you sew all four sides and you'll have perfect points. I hope I explained it correctly..
Larger triangle is easier to work with than having a triangle too small.
