NZQuiltler, I simply drew it out to make templates. This one is pretty simple because you can go a bit longer on the edges and trim to size once sewn. I make paper templates, stack fabric and glue the template to the fabric. I'll cut the template without seam allowance, then use my ruler lined up at the 1/4" mark and cut with rotary cutter. If I need to cut a lot, I use the piece of fabric with the pattern on it as the next template.
I do have EQ8 and will use that to get templates when I've got something a bit more complicated, but often it's less work for me to make a scale drawing while at the cutting table than to go fire up the computer down in the study.
