- Place your 4-1/2" x 9" background strips on a rotary mat, all edges aligned and right sides together. Cut a 45-degree angle in the end of the strip sandwich as shown, beginning the angle's tip 8-7/8" from the bottom left edge. The ruler's 45-degree line should be aligned with the bottom of the strip.
Don't worry if your length is not exact -- as long as it's longer than required, not shorter.
- You should now have two mirror image trapezoids as shown.
- Find one brown and one background half-square triangle created by cutting 4-7/8" squares in half once diagonally. Sew together along their long edges and press the seam allowance towards the dark half. (Step not illustrated)
- Referring to the illustration as guide, sew the unit you just created to the bottom edge of a trapezoid. Double check placement before you sew. Press the seam allowance towards the background unless it is very sheer.
- Sew your remaining large brown triangle to the second trapezoid as shown in the illustration, matching their 90-degree angle sides (shown as the bottom edge) for sewing. Press the seam allowance towards the background unless it is very sheer.
- Sew the two base units together, matching seam intersections carefully. Press. (see page 3 for a visual)
