Hi Gwen,
There is a way to take the pattern right off the quilt. You would press one of the blocks so that it is as straight as you can get it. Then use a piece of tracing paper to mark all of the seams lightly. Take that to your desk and neaten it up onto graph paper.
Once you have that label the pieces either by using 1 through whatever or alphabetical. This keeps all the pieces straight and makes sure you know the top side of the templet. You can also add what color it is to be to each templet piece.
. Take a copy of the finished block for reference. Then cut it apart. You then use this pattern to cut the fabric out ADDING A QUARTER INCH to the pieces as you go. Or, you can transfer the blocks onto the graph paper again and add the quarter inch for a complete templet.
