KEEP THAT DRESS ON YOUR SHOULDER!
Added Jul 31, 2010
At one end of the strip stitch one of the snap fastener's pieces. The
other end of the strip - fix it on the shoulder line on the inside of
your garment, close to the edge, preferably to the seam allowance so
that the threads don't show on the outside.
On the garment stitch the other element of the snap fastener, on the shoulder line, to the inner seam allowance.
