Yea a different color certainly helps. I played with 3 colors of paracord last night. A color each for the foundation, 1st interweave and 2nd interweave. I think I found where I was going wrong before you have to cross over the 1st interweave when you turn back or you are on the wrong side to properly split the pairs. Now I guess I'll have to cut off the buttons and give it another go.
Here is a picture of the hobbles with the screwed up buttons, they don't really look to bad from a distance or if you don't know what you are looking for.
