I recently made a colorful selvedge. It is 4.5 cm wide. It was supposed to be 9 m long, which is half a meter more than I had managed to make using elements of housing infrastructure. It turned out that it was enough to make a certain modification to the way the warp was wound. The selvedge came out with a margin, because it is almost 10 m long. I estimate that now I could easily make selvedges even 14 meters long here.
However, the length of the selvedge is inversely proportional to the pleasure of weaving, and directly proportional to boredom and the number of ideas that arise as to what better thing one would like to do with the time devoted to a given selvedge.
