One yard of oilcloth, one yard of poly-cotton broadcloth (for the back), two packages of extra-wide double fold bias tape and about an hour of cutting, pinning and sewing. One package of the bias tape went around the straight edges on the left, bottom and right (all in one piece, with mitered corners), and the short straight edge at the top. The other package makes up the neck strap and the ties and binds the curved armholes – and neatly covers the raw edges from the other bias tape. So much faster to buy the prefolded bias tape and not have to do all that pressing!
