In 1950-2, my grandmother, a dressmaker, made these invisible wool mending sampler.
The first sampler is a thin, plaid wool fabric with three different mends.
The first mend is set between the stripes, so the seams are hardly noticeable.
The second mend goes across the stripes.
The third mend is the whole placket of the sampler.
Because the wool fabric frays, all the raw edges are finished with tiny buttonhole stitches by hand.
To make the placket, a new piece of fabric is added. On the right side, it is joined by a seam; on the wrong side, the fabric pieces are again joined by tiny hand-sewn buttonhole stitches.
Sampler 2 is again a thin, but solid colored wool fabric with a triangle and a square mend.
The raw edges are also finished with hand-worked buttonhole stitches.
The third sampler is a thick boiled wool fabric with two mends.
Because the fabric doesn’t fray, the edges are left unfinished.
