The term originated from the occasional black sheep which are born into a flock of white sheep due to a genetic process of recessive traits. Black wool was considered commercially undesirable because it could not be dyed. In 18th and 19th century England, the black color of the sheep was seen as the mark of the devil.
The transom is the flat back end of a boat. Some boats are pointed on both ends, so they have no transom. A traditional canoe, pointed on both ends has no transom. A modern square stern canoe (made to take an outboard motor) has a transom.
What is Tapestry? Tapestry is a type of fiber weaving. It is weft-faced (ie: the warp does not show at all), the wefts are generally discontinuous (they do not go from selvedge (edge) to selvedge (edge) and it is generally pictorial (like painting a picture with fiber).ow do I know what warp coil to use for tapestry? This is something you have to experiment with as a tapestry weaver. For finer weft, you will want to use a warp coil with more dents per inch. For thicker weft, you will want to use a warp coil with fewer dents per inch or even warp every other dent.
