Thanks to Nicolette, Crystal, and everyone's encouragement, I achieved my “ah hah” Oprah moment with the Sew Pretty Homestyle bag (page 26) that flummoxed me last week.
The sunlight makes the bag and rose look blue—the correct purple color is more accurate in the last photo showing the rose.
My mistake was that I did not pull the lining fabric through the top opening of the bag as illustrated in Figure B of the book before drawing the corner arcs on both ends and sewing. Purely operator error on my part.
This is what the interior looks like.
I also managed to make the decorative rose and accompanying leaves (page 69) without problem. I’m so relieved.
