When you think about it , what was you doing wearing jeans working in a custys house?
certainly not something I would do, I dont think it portrays the right image .
You should really have been aware of the fact that dye from jeans is suspect to migration, look at most leather suites and there will be signs of dye from jeans.
Finaly , Why was you not using drop sheets , this would have prevented the problem.
Still, as you say , you have learnt a lesson, and warned others of the danger, like most of us do throughtout our chores.
Some things are simply overlooked , I know we have all done it
