SQUARE IN A SQUARE technique ruler

I wanted to give just a quick idea on how the square in the square ruler technique works, The book patterns and dvd give you precise detail of course..but I just love the idea of  Never having to sew or cut a triangle !  Nothing could be better easier  more accurate or faster, Using squares and strips to make a square in a square block, or half square triangles, or flying geese units,...

First you start with a square, ( I used a 3 1/2 inch square and 2" strips,) then you stitch your square to a strip, I clothesline sew to save time, so I lay my squares on a strip and sew using 1/4" seam on to one side of the strip, and then sew a strip to the opposite side, then the top and then the bottom, I think of it as east west north and south,

Now using the square in a square ruler  place the 90 degree on tip of your square you simply trim each corner and you have a perfect square in a square !  How easy is this?

There are many options such as flying geese and half square triangles that you will enjoy, what I have shown here is the basic option 1,  Next time I will show option 3 "flying geese units" !
