Page 1 of 3 - Paracord Dog Collar - posted in DO-IT-YOURSELF (DIY): Finished up a collar for one of my dogs today, used a ladder rack knot. For a 15.25" collar I used 23 ft total of paracord in 2 colors, but one single color can be used. It takes about 1.5 of cord for every finished inch of collar. Im super stoked at how well it came out. Here are a few pics of the process.
