How tweed behaves on a blazer
In a blazer it holds a strong shoulder and a straight front almost without help from the canvas.
At this length a structured cloth holds the shape of the pattern from top to hem.
It wears warm, which places it in autumn and winter collections.
The finished piece is usually labelled dry clean only.
It is very hard-wearing and sheds light rain, but heavy tweed is bulky at the seams and stiff at first.
About tweed
Tweed is a rough, warm woollen cloth woven from yarns dyed before weaving, which gives it its flecks and its checks. It was made for the outdoors and remains one of the most durable cloths.
Harris Tweed is hand-woven in the Outer Hebrides of Scotland and carries its own certification mark; most other tweeds come from Scotland, England, Ireland and Italy.
Tweed jackets, coats and skirts are lined in viscose or cupro, for comfort and so the cloth does not catch.
Cutting, sewing and color
A 90/14 needle; match the check or the stripe at every seam, and tape the edges so they do not stretch.
Its color comes from yarns dyed before weaving, so the flecks are part of the cloth, not printed on it.
Its surface is matte, so it photographs evenly under flat light.
