The geometrical patterns of woollen blankets or patchwork quilts have a lot in common with mosaics. They are based on the same idea of making an image from small areas of colour joined without spaces. In patchwork the pieces are sewn edge to edge (see Topic 3, Example 1). In weaving, the cloth is made up of threads that cross one another so one shows at a time.
Wales has a tradition of weaving patterned blankets (see also Topic 11 Example 1). Modern designers like Melin Tregwynt in Pembrokeshire continue the tradition. Their website has films about how they design and weave (in English).
