50 feet, braided into something decorative? Wow, that's a lot of work and a long braid.

I have a couple of braided landyards of 150 lb. test cord, one I keep on my key chain. To braid it, I used two pieces of cord, each about 5 feet in length. These braids end up being about 8 inches in length. Using 50 feet of cord, cut into two 25 foot lengths, the braids would be about 4 feet long. Yikes.
