Using a protractor, find the angle of the pieces in relationship to the sides of the blocks. Then cut the strips on that angle. Sew all strips together and then use your square ruler with the angle marked (use a piece of 1/4" tape if it's not an angle already marked on the ruler) and cut out the size squares you want.
Bingo---the edges of the block should now be on straight of grain.
Is that clear as mud?
