I was constructing the skirt from the Sunday Brunch pattern. Before I started I had checked for errata on the site. The errata indicated that I should add an inch to the waistband piece for the size I was making, so I did. However, when I got to the point of attaching the waistband to the skirt I ended up with two extra inches of waistband, exactly the amount added to the pattern when cut on the fold. Is it possible my pattern had the correct pattern piece in it already?
