The second option is overcasting and we do this if fringes are too short and unraveling may damage the design. Below, I am posting pictures of an overcasting job for an antique Isfahan rug. The quality of the jobs posted here is very high that one may think these are done by machine. One of our repair masters who has been in rug restoration for over 40 years, has done the securing and overcasting of these two rugs.
