Ron and anchorites,

The folks who store archival photographs and documents shriek in horror at 
most label adhesives and especially rubber cement.  The ingredients attack 
paper and fibers.  Our radio dial cords are perhaps not irreplaceable 
artifacts to be stored under archival conditions, but it's worth noting the 
materials we use.

My solution (pun intended) is a saturated solution of rosin in 
alcohol.  The rosin comes from the sports store, the alcohol from the drug 
store.  I paint a bit upon the string wherever it needs it and that stops 
the slipping.

Ron's tale does show us that we might want to pre-stretch the cord, any 
advertising claims not withstanding.

Roy
