One popular way to carry it around with you is to weave it into a bracelet. I got one such bracelet from eBay for about $3.
I also got some loose paracord of the same colour. I don't know if it's just mine or all reflective paracord is like that, but handling it leaves this grey powder on your hands. It's like if you use your hands to rub one of those scratch-and-win surfaces. Maybe it's the reflective coating coming off. Doesn't seem to affect the reflectivity though. If you're going to handle it a lot, I recommend not getting a reflective colour.
I think any method of carrying paracord should have these properties:
- Quick to deploy (most methods do not have this, most notably cobra weave, which is used in all the articles shown here)
- Deploy from only one end (I haven't seen anyone mention this. If you need 1 m of cord, you should only have to unravel 1 m, not 1 m from each side for a total of 2 m.)
