Yolanda, I like the red and blue. It's right, but I found that if you sewed in stipes then sewed the strips togethor it was easier. I sewed the down the seams (ovals) of the strips before I joined them, then sewed down the long seam.
Matching points was a bear at times and for me it was easier using the strips.
Denim gets heavy and it's stiff so it was a bit cumbersome to finish up those last few rows.
