Currently in progress a quick project of a waterfall jacket. It is from Prima Magazine Feb 2006 and is basically a rectangle with sleeves inserted into oval armholes. There are no facings, closures etc so super simple to sew.
It has a very different silhouette than I am used to having but that is not necessarily a bad thing.
Mine is made in soft black wool fabric (woven) which drapes nicely.
I will do some photos at some point over the weekend.
