tip #26 putting the blocks backwards on the design wall

Sometimes I am really persnickety about not twisting seam allowances.
Not very often--I am usually quite laissez faire about it, to the point of calling the flipped seams "twisted sisters".
But, on the occasion it does matter to me, I put my blocks up backwards on my design wall. This way I can watch the seam allowances and make sure I am putting the sections together in a way that keeps the seams from twisting.

As this picture shows, the spools are all getting put together!
