Reflectors - to keep or not to keep?

[dex]

We have a fabric store around here that sells technical fabrics. (like Cordura, nylon for making tents - Gortex type materials, neoprene) They also have a huge selection of reflective items. They have iron on, sew on and self stick tapes and sew in reflective piping.

Ok, slightly off-topic. Sorry, but...

Where?? I just had a conversation this morning over breakfast where someone was wondering where they might be able to buy those kinds of fabrics. Specifically, we were talking about tents.
