Have you received the pattern yet? Is there a pattern within the pattern that gives you the template for the cutting? You could make your own with template plastic and a Dream Seamer (TM) to mark the 1/4" seam lines.
Dream Seamers are a tiny brass disk with a hole in the center. From the hole to the edge is 1/4". You put a pencil point in the hole, place the seamer against the edge of the template, and draw around the template. Joanne's used to have them, may still.
