Here's a cardinal block which you can print and try out the technique. Place freezer paper dull side up over pattern and trace all lines. Transfer letters and numbers to freezer paper copy. The letters correspond to the fabric key, and the numbers indicate piecing order. Cut up freezer paper pattern to make your templates.
Bold lines indicate major sections.
Cut these apart first. Then cut apart on dotted lines. You now have subsections. Cut only one subsection apart at a time. Press freezer paper templates to wrong side of fabric, using the key to select your fabrics.
