It's some sort of Holiday after the end of the Mayan world calender ran out..
There are self adhesive reflective tapes , and if the fabric is a PVC coated on the outside ,
stuff that goes on Raigear for the Fishing workers sticks good.
You might kludge an Iron on combination on cloth faced coated on the back fabric.
I could easily dig around in the old relectors in the LBS
and use a few bits and Pieces from the hardware store , and make something work,
so I am puzzled by those who cannot do simple Mechanical combinations .
Designing improvised solutions, as I see the Bins of stuff in the Store..
