The patterns that I show here are made on a loom with two shafts allowing only very simple patterns.
The woven sample is an idea for an ‘outdoor carpet’. The yarn consists of a filament yarn with extra chemicals added to the polypropylene spinning mass causing the yarn to be water repellent, fungus-free and UV-resistant.

Each warp thread passes through a heddle bar, an eyelet in a shaft, and then through a reed. The shafts can move up or down leaving room for the weft thread. The shafts that move the warp threads up or down determine the definitive pattern.
When the patterns become more intricate you need to use a Dobby or jacquard loom.
The most famous pattern made with the Dobby, is the chequered tea towel. The Dobby has up to 32 shafts with which to weave patterns.
