CW wants a demo of my technique with freezer paper

What I do is very simple and is less wasteful of fabric.  
Often times I see a pattern in a magazine that I really like, but it is for a 9 inch block instead of 12,  and all the directions for cutting the pieces is for that 9 inch block.
So I draw off the pattern onto a 12 inch piece of freezer paper (you can cut it easily with a rotary cutter on you matt.  This is cake plate from the Fall colors swap.  I number the pieces for the colors I will use 
Then I cut up the pieces and gather together the same color pieces.   I then position these onto white fabric.  (For this example I'm using a colored fabric so the white paper shows up.)  I position them with  the seams between and use a ruler to line them up.   I iron these to the fabric.  What I'm looking for is the most condensed arrangement that yields the pieces  with the added seams
Here I was able to combine three pieces from the corner into one larger triangle.
Next I arrange all the same color pieces together on the matt board and make notes of the sizes of the fabric pieces on the original pattern.  Now I know how wide to cut my strips for cutting out the component pieces.   Here a 7 inch strip will yield the triangle  corner and the two rectangles.  
There were four triangles and a 3 inch square for color 1.  By playing with the triangle pieces, I could cut a 5 5/8 inch  square to cut on the diagonal twice.  
The three inch square with seams would be cut from a 3.5 inch strip.  The color 2 I decided to make from a rectangle since I wanted to use two different swatches for those pieces.  The two together for each swatch could also be cut from a 3.5 inch strip at  4.5 inch. 
The hour I might spend in the drafting process is worth it.  I use old cotton pillow cases or an old sheet for the drafting process so I'm not cutting up my good quilting fabric.  I can stitch these pieces together to make a practice blick and tweek the pieces before I ever cut into my good fabrics.  I make notes on the original pattern and can use it to sight measure my block as I work with it. 
I hope this helps.
