Create a grid on your light fabric strip or on a paper template.
- Use a rotary ruler to mark square segments along the length of the grid. The distance between each vertical line is the same as the width of the strip. Align a rule line with the edge of the strip before you mark to make sure all vertical lines are perpendicular with the top and bottom of the strip.
- Align a 45-degree line on a square or long ruler with the top or bottom edge of the strip and draw a diagonal line to connect the first two vertical lines. See the photo on Page 1 and refer to the illustration above.
- Repeat to connect the next two squares, but this time draw the line along the opposite angle as shown. Continue marking until all squares are joined by diagonal lines moving in an up and down manner along the grid.
- If you have a 1/4" presser foot you needn't mark the grid any further. If you do not have a 1/4" foot, use your rotary ruler to draw lines that are a scant 1/4" from each side of the angled lines you've already drawn. The new lines are seam lines.
