I have an U-shaped work area. I put an eye bolt on the 2x4 just under the counter top on one side and drilled a series of holes in the 2x4 straight across from the eye bolt 2x4. I then use a J hook and a screen door spring with an S-hook attached to both ends of the spring. I hook one end of the spring S-hook to the string and then to the eye hook and then stretch the string across to the other work bench putting a good amount of tention on the string. I insert the J-hook into the appropriate hole securing the J-hook to the 2x4 with a nut. I then attach the other end of the string to the spring's S-hook and stretch it across to the J-hook and slip the string loop onto the J-hook. I put my serving on while it is stretch holding onto the string so it doesn't twist while the serving it put on.
Man I hope that wasn't confusing but this system works great.
