I make lanyards and fobs out of paracord to keep my hands busy. The big question is the color...aesthetics you know. Next is nylon or polyester construction, as they work a bit differently. It's mostly personal preference, try a bit of both and see what you like. Last is the number of strands, with 5 being average. I like 7 strand cord for a fuller feel and greater tensile strength, but five will do fine for most things. I just think the 7 covers a 1" bearing a bit easier and is slightly firmer for knots. Again, it's all personal preference, try a grab bag of different compositions and see what works for you.
