Pardon my grumping in the last post. One is done and the other is half done.
I was trying various things and getting frustrated until I remembered that I have some solid 22 gauge copper "buss wire" on a 1/4 pound roll. Tinned silver color and smooth as silk. I was able to track this down quickly (unlike -some- things in my shop) - I cut off 24 inches and folded it in half and it was an absolutely perfect fish tool just like you are showing with the steel drop ceiling wire. All I can say is that it worked perfectly and a 12 inch fish tool was fine (since for the 10 inch section you compress the amsteel shorter than 10 inches when fishing.)
I added a nice turquoise blue bead to each like I see in some pictures of whoopie slings. Had a bag of beads handy so why not?
Feeling good about this, you made it easy - thanks.
