The first piece, CF panel, was easy. I made sure the stripe went in the upward position. I used the cut fabric as the pattern for the mirror image of the second side. I managed to line up the stripes easy enough for perfection. In preparing to sew CF, I carefully pinned each strip, so lots of pins were involved. I attached my walking foot to my machine to avoid slipage. Things went smoothly, and I was very pleased with the result.
My next challenge were the front two side panels. Again, I cut one panel at a time. A difference was making sure the stripe went in the downward position. Again, one fabric side was used for the pattern of the other.
Today I sewed the two side panels to the front. Up to the bust line the stripes matched perfectly. Impossible from then on. I love top-stitching, but I changed my mind about adding it to this dress. I don't want the stitching to distract from the bevels. So far so good.
