I'm stupid. I pull the entire core out, and stuff in a different color, just because I'm a douche, and like having things that aren't off the shelf. But yeah, it takes some patience to pull the dyneema through that tight weave.

The more you do it, the better you get. I could make a halyard in 15 minutes at one point. I haven't had to do it in at least a year and a half, but my spare is gone, on the boat, and it's looking tired, so time to make a couple more for myself. I'm sure it'll go swimmingly....
