I came across a pretty border print cotton when gathering fabrics for the Ronald McD Pillowcases and decided it would be perfect for a springtime version of the tunic nightgown that I made last from stripe flannel.
There is no piecing involved with this one. I just laid the major pattern pieces on the cross grain to take advantage of the teacup border. The fussiest part of the sewing was the neck facing due to the slit, but that's a minor quibble because the rest was so easy to do.
I sacrified the lower band of the border due to the curved edge on the sleeve hems. The pattern piece below shows the curve:
As you can see on the reverse, that lower band is all over the place due to the curve, and no way to fix it without major gyrations.
