When you get to the end of your piece of weaving what do you do with your end. Here is one suggestion.
On the second to last pic, on the side where the last pic will exit, place a loop of thread in the shed for about 2 - 4 inches (5 - 10 cm) with the cut ends sticking up from the cloth.
After weaving the last pic insert the cut end of weft into the loop at the selvedge and carefully pull it back into the body of the cloth pulling from the cut ends. (Sometimes you have to fudge if both the weft and loop exit on top or bottom of the warp thread.)
