When the treadling draft is exactly the same as the threading draft, we say the draft is treadled “tromp as writ.” Sometimes, only the threading is given and the words “treadle as written” or “treadle as threaded.” Tell you to tromp as writ.
Here is an example of a draft that is treadled tromp as writ.
You can tell because the blocks in the drawdown draft are squared.
The illustration shows the treading is the same as the threading.
You can “tromp as writ” in other ways, too. For example, you can use the order the colors were used in the threading for the order of colors in the treadling. That sequence would make a plaid.
